“…The value of the band gap was observed to increase from 4.35 eV to 4.68 eV after the incorporation of the Ho 3+ activator ion. This rise in the band gap value could be attributed to the high optical band gap of RE ions [32]. The calculated band gap value suggests that the synthesized phosphor fell within the category of wide band gap semiconductors, making it suitable for various photonic, lasing, and optoelectronic applications [33].…”

“…This analysis technique quantifies atomic parameters, unit cell volume and density, and the chemical occupancy of the constituent atoms. 30 The FullProf program was used to carry out the refinement on the XRPD data of pure LiGa 5 O 8 , and a CIF file (1007185) obtained from the crystallographic open database was used as an initial input data file. The pseudo-Voigt function was used to determine the peak pattern, and a linear interpolation technique was used for determining the background of the input data.…”

“…Other advantage of this synthesis method is that no toxic gases or waste are generated during this procedure. However, this method suffers from disadvantages such as the need for higher temperatures, a longer duration of time, weak surface morphology, low dispersibility, and homogeneity [ 265 ]. With solid-state reactions, the yield is quite good, which makes it an ideal technique for large-scale production.…”

“…With solid-state reactions, the yield is quite good, which makes it an ideal technique for large-scale production. This technique has been most widely used for the synthesis of PerLum nanophosphors because of its already discussed advantages [ [265] , [266] , [267] , [268] ]. While discussing the mechanism of LLP, as already mentioned, traps and emitters are of primary importance for this phenomenon, and high temperatures have proved very helpful for inducing lattice defects, distortions, vacancies, intrinsic defects, etc.…”
