Polycrystalline La0.8Sr0.2GaO3 perovskite synthesized by sol–gel process along with temperature dependent photoluminescence

Phase transition in Cu2+xSnS3+y(0 ≤x≤ 2; 0 ≤y≤ 1) ternary systems synthesized from complexes of coumarin derived thiocarbamate motifs: optical and morphological properties

“…These values are relatively lower than the nominal indicating that the stoichiometric compositions have been achieved. 25 Fig. 6 shows the Rietveld renement for our compound indicating a good agreement between observed and calculated proles.…”

Correlation of crystal structure and optical properties of Ba0.97Nd0.0267Ti(1-x)WxO3 perovskite

“…However, it is likely to consider only direct transitions for most of the pervoskite ceramics. 42,43 Therefore, eqn (1) becomes:…”

The structure and photoluminescence of a ZnO phosphor synthesized by the sol gel method under praseodymium doping

“…the distribution of traps in the material. 68,69 The incorporation of Pr 3+ ion affects at least as much the substance's order as the structure impurities in ZnO. 70…”
