Crystallographic and photophysical aspects of combustion derived novel Dy3+-activated BaSrGd4O8 nanophosphor for advanced solid-state lighting applications

Green emission from trivalent cerium doped LaAlO3/MgO nano-composite for photonic and latent finger printing applications

“…8(c) . 51 These peaks arise due to 5d → 2 F 5/2 and 5d → 2 F 7/2 transitions as indicated in schematic energy diagram ( Fig. 8(d) ).…”

“… 59 Upon Ce 3+ doping, E g of optimized nanophosphor (La 1− x Ce x AlO 3 /MgO ( x = 0.9 mol%)) and La 1− y Ce y AlO 3 ( y = 0.9 mol%) reduces to 5.53 and 5.66 eV because of extra electronic state occurrence within the host bandgap. 51 But reduction in prepared doped nano-composite is considerably large which results in PL emission wavelength shift relative to individually doped LAO. This justifies the advantage of prepared nano-phosphor composite over individually Ce 3+ doped LAO.…”
