It is challenging to rational design persistent luminescence and storage phosphors with high storage capacity of electrons and holes after X-ray charging. Such phosphors have potential applications in anti-counterfeiting and X-ray imaging. Here we have combined vacuum referred binding energy diagram (VRBE) construction, photoluminescence...

There are various routes of luminescence quenching such as multi-phonon relaxation from excited states to lower energy states, energy migration to killer sites, and radiation less relaxation to the ground state via the crossing point in a configurational coordinate diagram. In this work, we will consider and review quenching of lanthanide...

Fast energy transfer from Yb<sup>2+</sup> to Sm<sup>2+</sup> is a requirement when using Yb<sup>2+</sup> as a sensitiser for Sm<sup>2+</sup> emission for near-infrared scintillator applications. This cannot be achieved through dipole-dipole interactions due to the spin-forbidden nature of the involved Yb<sup>2+</sup> transition, making the...

Ce3+-doped LiSr4(BO3)3 phosphors have been prepared by a high-temperature solid-state reaction method, and structural refinement of the host compound has been performed. The excitation and emission spectra in the vacuum ultraviolet-ultraviolet-visible range at cryogenic temperatures reveal that Ce3+ ions preferentially occupy eight...

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...

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...

In first approximation the binding of an electron in lanthanide 4f<sup>q</sup> ground states changes with q in a characteristic zigzag shape that is independent on type of compound. Those shapes have been parameterized in past publications and are used to construct host referred binding energy (HRBE) or vacuum referred binding energy (VRBE)...

Information on the 5d level centroid shift (ϵc) of rare-earth ions is critical for determining the chemical shift and the Coulomb repulsion parameter as well as predicting the luminescence and thermal response of rare-earth substituted inorganic phosphors. The magnitude of ϵc depends on the binding strength between the rare-earth ion and its...
