There has been a renewed interest in Ce3+‐activated halide phosphors due to applications as scintillation detectors, especially for positron emission tomography. For K2LaCl5, the light yield increases and the energy resolution (FWHM) improves with increasing Ce3+ doping. K2LaX5 compounds are also important as laser hosts for the mid‐IR range. K2LaCl5:Nd crystals show bright mid‐IR luminescence, which...
In this study, using a simple combustion process and a wet chemical process, fluorides showing intense photoluminescence were prepared and developed as low‐cost phosphors. The prepared phosphors were characterized by photoluminescence (PL) techniques. PL emission spectra of the phosphor suggest the presence of Eu3+ as well as Eu2+ ions in LiMgBF6:Eu and Li2NaBF6:Eu lattice sites. This article summarizes...
