Abstract
Eu3+:YVO4 red and Ce3+, Tb3+:LaPO4 green phosphors were prepared by ne wly discovered hydrolized colloid reaction (HCR) technique at low temp erature (<100 degrees C) and atmospheric pressure utilizing subsequent calcining and reductive treatments, respectively. The incorporation o f activators (Eu3+ and Ce3+, Tb3+) in these very porous powders was ch ecked by X-ray diffraction (XRD), scanning electron microscopy (SEM) a nd luminescence investigations.
