Description :
Compound Sr3Al2O5Cl2 doped with various concentrations as 0.1, 0.3, 0.5, 0.7, 1 mol% of rare earth dopant Sm3+. These
phosphors were synthesized by using solution combustion method. Photoluminescence (PL) emission spectra shows
highest intensity emission peak at 566nm and 604nm for 0.3 mol% Sm doped phosphor at 405 nm excitation wavelength.
0.3 mol% Sm doped phosphor further doped with calcium nitrate shows highest intensity emission peak at 566nm and
604nm for the phosphor Sr0.5Ca2.5Al2O5Cl2: Sm 0.3mol% where the emission intensity increased 1.5 times. The studies
showed that these phosphors are promising candidate for the light application. Commission International deI’Eclairage
(CIE) chromaticity colour coordinates of these phosphors were calculated. CIE- Chromaticity colour coordinates of this
phosphor shows orange-red emission.
