Rare earth activated phosphors are largely used in optoelectronic devices, X-ray intensifying screens and fluorescent lamps. Luminescent properties (colour, efficiency, and decay parameters) and powder characteristics (particle morphology and size, crystalline structure) that are regulated during the synthesis process determine the phosphor utilisation potential. Photoluminescence (PL) and cathodoluminescence (CL) investigations are used in order to evaluate the quality of phosphor based on europium and terbium activated calcium tungstate. CL and PL spectra as well as CCL-SEM pictures of some CaWO4: Eu,Tb samples are discussed in relation with some of their preparation parameters. The mutual interaction of the two activating ions is put in evidence |
