| Abstract: | The synthesis route at low temperature for Ce-doped yttrium
aluminium garnet (YAG:Ce) phosphor is described. Its photoluminescence
efficiency and quenching temperature dependence characteristics are found to be
comparable to the imported one. YAG:Ce shows least thermal quenching among the
several blue LED phosphors [CaS:Eu2+, (Y,Gd)3Al5O12:Ce3+,
SrS:Eu2+ and SrGa2S4:Eu2+]. |
