In the field of solid-state luminescence, Cu<sup>2+</sup> has long been widely acknowledged for its capacity to emit infrared light. However, the occurrence of visible emission from Cu<sup>2+</sup> ions had been infrequently observed and reported. In this study, we made an intriguing discovery by examining the behavior of Cu<sup>2+</sup>...

The characterization of a wide range of luminescent thin films can be a long and tedious endeavor. With reactive combinatorial sputtering of multiple metal targets, it possible to fabricate thin films with a gradient in composition simply by not rotating the substrate. In this work, combinatorically sputtered thin films of Cr<sup>3+</sup> and...

Lead halide perovskites are reportedly a very promising group of materials for scintillation due to their fast sub-nanosecond exciton luminescence, small band-gaps, and high theoretical light yield. Unfortunately, they only show emission at cryogenic temperatures. In this work single crystals of CsPbBr<sub>3</sub> and CsPbCl<sub>3</sub> are...

Discovering bismuth based smart materials that can respond to thermal, mechanical, and wide range X-ray to infrared photon excitation remains a challenge. Such materials have various uses like in advanced information encryption. In this work, valence state change between Bi<sup>2+</sup>, Bi<sup>3+</sup>, and Bi<sup>4+</sup>, and the dual role...

Temporal dynamics of confined optical fields can provide valuable insights into light–matter interactions in complex optical systems, going beyond their frequency-domain description. Here, we present a new experimental approach based on interferometric autocorrelation (IAC) that reveals the dynamics of optical near-fields enhanced by collective...

Multimode luminescence relates to how charge carriers are transported and recombined in response to various physical excitations. It shows promising applications in many fields like advanced anti-counterfeiting, information storage and encryption. Enabling a stable single compound with multimode luminescence is a unique technology but still...

Indium phosphide colloidal quantum dots (CQDs) are the main alternative for toxic and restricted Cd based CQDs for lighting and display applications. Here we systematically report on the size-dependent optical absorption, ensemble, and single particle photoluminescence (PL) and biexciton lifetimes of core-only InP CQDs. This systematic study...

Ytterbium-doped LiYF4 (Yb:YLF) is a commonly used material for laser applications, as a photon upconversion medium, and for optical refrigeration. As nanocrystals (NCs), the material is also of interest for biological and physical applications. Unfortunately, as with most phosphors, with the reduction in size comes a large reduction of the...

The quest for new materials for thermoluminescence (TL) and optically stimulated luminescence (OSL) dosimetry continues to be a central line of research in luminescence dosimetry, occupying many groups and investigators, and is the topic of many publications. Nevertheless, it has also been a research area with many pitfalls, slow advances in...

This work presents a fresh insight into the excited charges trapping in the Lu<sub>2</sub>O<sub>3</sub>:Tb,M (M= Ti, Hf) ceramics and their characteristics as storage and/or persistent luminescence phosphors. The results were obtained by applying an exceedingly versatile set of experiments based on thermoluminescence and thermoluminescence...

Tm<sup>2+</sup>-doped halides exhibit excellent properties for use in Luminescence Solar Concentrator (LSC) applications. Such LSCs consist of a glass waveguide with small Copper-Indium- Selenide (CIS) solar cells attached to its edges. The waveguide contains a luminescent coating based on a Tm<sup>2+</sup>-doped halide, whose 4f125d1 absorption...

The parameters governing the performance of a luminescent solar concentrator (LSC) are determined for sputtered thin-films of NaI:Tm<sup>2+</sup>, CaBr<sub>2</sub>:Tm<sup>2+</sup>, and CaI<sub>2</sub>:Tm<sup>2+</sup>. These parameters are determined by using six gradient thin film material libraries, combinatorially sputtered from metallic...

Electron microscopy is crucial for imaging biological ultrastructure at nanometer resolution. However, electron irradiation also causes specimen damage, reflected in structural and chemical changes that can give rise to alternative signals. Here, luminescence induced by electron-beam irradiation is reported across a range of materials widely...

The prospect of using Tm<sup>2+</sup>-doped halides for luminescence solar concentrators (LSCs) requires a thorough understanding of the temperature dependent Tm<sup>2+</sup> excited states dynamics that determines the internal quantum efficiency (QE) and thereby the efficiency of the LSC. In this study we investigated the dynamics in CaX<sub...

Polymer glasses have an irregular structure. Among the causes for such complexity are the chemically distinct chain end groups that are the most abundant irregularities in any linear polymer. In this work, we demonstrate that chain end induced defects allow polymer glasses to create confined environments capable of hosting small emissive...

Upon his retirement from science Blasse wrote a paper (Blasse, J. Lumin. 72-74 (1997) 129) addressing unsolved problems in explaining luminescence phenomena of classical phosphors. He used the metaphor of Pandora's box. A box full of disaster that should remain closed. Yet, Blasse did open that box and therewith spread the unsolved problems...

A luminescent solar concentrator (LSC) is a concept from the 1970s that can find novel application as an electricity-generating window. An LSC converts sunlight to light of a different color by a process called luminescence. This light is transported to the edges of the LSC, where photovoltaic cells convert this incoming light to electricity....
