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 luminescence properties of Tm2+-doped BaCl2 with an orthorhombic structure have been studied as a function of temperature and compared to other Tm2+-doped chlorides. In addition to the 2F5/2 → 2F7/2 (4f13 → 4f13) line emission, two 4f125d1 → 4f13 band emissions are observed at 20 K that can be ascribed to the spin-allowed (3H6,5d1)S=1/2 →...

The cyan-emitting BaSi<sub>2</sub>O<sub>2</sub>N<sub>2</sub>:Eu<sup>2+</sup> phosphor is a promising narrow-band and high-efficiency luminescent material used in wide-color-gamut white light-emitting diodes (wLEDs). However, its serious degradation under thermal attacks hinders its practical applications and needs to be improved. Herein, we...

The photocatalytic mechanism of TiO<sub>2</sub> (P25) nanoparticles coated with SiO<sub>2</sub> (SiO<sub>2</sub>:TiO<sub>2</sub>) by atomic layer deposition was investigated. The deposition of SiO<sub>2</sub> on TiO<sub>2</sub> not only gives a photocatalytic improvement for the degradation of both Rhodamine B (3.6–fold) and Acid Blue 9 (3...

The red afterglow of current rare-earth-activated long persistent luminescence (LPL) phosphors is largely still less than 6 h, in contrast to the 20 or 30 h long blue- or green-emitting ones, becoming the main obstacle to realize their multiscenario applications in practice. Herein, we report a rare-earth-free red-emitting LPL phosphor SrGa...

The role of Pt on photocatalytic substrates such as TiO<sub>2</sub> (P25) for the decomposition of organic pollutants is still controversial in the scientific community. The well-observed behavior of an optimum catalytic activity as a function of the Pt loading is usually explained by the shift from charge separation to charge recombination...

Phosphors with high quantum efficiency and thermal stability are greatly desired for lighting industries. Based on the design strategy of solid solution, a series of deep-blue-emitting phosphors (Sr<sub>0.99-x</sub>Ba<sub>x</sub>)<sub>2</sub>P<sub>2</sub>O<sub>7</sub>:0.02Eu<sup>2+</sup> (SB<sub>x</sub>PE x = 0–0.5) are developed.

Photocatalysts for water purification typically lack efficiency for practical applications. Here we present a multi-component (Pt:SiO<sub>2</sub>:TiO<sub>2</sub> (P25)) material that was designed using knowledge of reaction mechanisms of mono-modified catalysts (SiO<sub>2</sub>:TiO<sub>2</sub>, and Pt:TiO<sub>2</sub> ) combined with the...

Relations between the bandgap and structural properties and composition of the M–Si–N nitridosilicates (M = alkali, alkaline earth or rare earth metal) have been obtained, using experimental data collected from literature; and qualitative models are presented to explain the observed trends. Compounds with a higher degree of condensation, i.e. a...

Structural and optical properties of MGa2S4 (M = Mg, Zn, Ca, Sr, Ba) compounds have been compared, and the vacuum referred binding energy (VRBE) schemes were constructed for the lanthanide ions in the iso-structural compounds CaGa2S4 and SrGa2S4 employing literature data. The VRBE of an electron in the 5d excited state of Eu2+ was found at 0.75...

A series of Si-N or Eu-Li doped CeAl11O18 and CeAl12O18N phosphors are prepared by solid–state reaction. Their structure and luminescence are researched carefully. Si-N doping with the concentration less than 8% can be successfully dissolved into CeAl11O18 crystal lattice and doesn't change the matrix structure, only resulting in crystal lattice...
