Abstract

Green phosphor of Y(BO3, PO4): Ce, Tb was synthesized by means of the sol-gel and conventional solid state methods. The thermal formation process was characterized by the thermogravimetric analysis (TG) and (DTA). The effects of synthesis conditions on the crystal and morphological structures were investigated using the X-ray diffraction (XRD) and Scanning Electronic Mcirosocpy (SEM). The results revealed that Y(BO3, PO4): Ce, Tb phosphors with the monocline structure and high purity were successfully prepared by the sol-gel method. Furthermore, the products synthesized by the sol-gel method showed a well developed crystal structure, small particle size, narrow size distribution and high luminescent performances. The product synthesized at 1050 for 2h had better emission intensity..
