PREPARATION OF Eu3+:YVO4 RED AND Ce3+,Tb3+:LaPO4 GREEN PHOSPHORS BY HYDROLYSED COLLOID REACTION (HCR) TECHNIQUE

Eu3+:YVO4 red and Ce3+,Tb3+:LaPO4 green phosphors were prepared by a new HCR technique at low temperature (less than 100 C) and atmospheric pressure utilising subsequent calcining and reductive treatments, respectively. The incorporation of activators (Eu3+ and Ce3+,Tb3+) in these very porous powder...

Description
Summary:Eu3+:YVO4 red and Ce3+,Tb3+:LaPO4 green phosphors were prepared by a new HCR technique at low temperature (less than 100 C) and atmospheric pressure utilising subsequent calcining and reductive treatments, respectively. The incorporation of activators (Eu3+ and Ce3+,Tb3+) in these very porous powders was checked by XRD, SEM and luminescence investigations. 5 refs.
