Synthesis of Cerium-and Terbium-Activated Lanthanum Phosphate by Means of Microwave Heating and Its Luminescence Properties
Abstract:
The synthesis of(La,Ce,Tb)PO4 by means of microwave heating is reported. The analysis of X-ray powder diffraction data shows that the phosphor belongs to the monoclinic system with the structure of monazite.The phosphor has the maximum excitation peak at λex=273.5 nm and maximum emission peak at λem=543 nm,the latter being the characteristic emission of Tb3+ ion.The effects of different flux and(NH4)2HPO4 dosage on the luminescence intensity are examined and the chromatic coordinates and related chromatic temperature are measured.
