Ramachandra Naik,S.C. Prashantha,H. Nagabhushana,S.C. Sharma,B.M. Nagabhushana,H.P. Nagaswarupa,H.B. Premkumar +6 more
TL;DR: A simple and low-cost solution combustion method was used to prepare Eu 3+ (1 − 11 −mol%) doped Mg 2 SiO 4 nanophosphors at 350 −°C using metal nitrates as precursors and ODH (Oxali di-hydrazide) as fuel.

Photoluminescence, photocatalysis and Judd–Ofelt analysis of Eu3+-activated layered BiOCl phosphors
TL;DR: Eu3+-activated layered BiOCl phosphors were synthesized by the conventional solid-state method at relatively low temperature and shorter duration (400 °C for 1 h). All the samples were crystallized in the tetragonal structure with the space group P4/nmm as discussed by the authors.

Ag nanoparticles induced luminescence enhancement of Eu3+ doped phosphate glasses
TL;DR: In this article, a thermal annealing process was proposed to control the aggregation and growth of Ag NPs in Eu3+ doped phosphate glass containing silver nanoparticles (NPs) and the observed enhancement of photoluminescence and the PL lifetime relative to 5D0 → 7F2 transitions were explained not only by the energy transfer ions, but NPs to Eu 3+ ions but also by the enhancement of local field effect LFE induced by SPR of silver NPs.
