dc.description.abstractA novel green phosphor, Tb3+ doped Bi2ZnB2O7 was synthesized by conventional solid state reaction method. The phase of synthesized materials was determined using the XRD, DTA/TG and FTIR. The photoluminescence characteristics were investigated using spectrofluorometer at room temperature. Bi2ZnB2O7:Tb3+ phosphors excited by 270 nm and 485 nm wavelengths. The emission spectra were composed of three bands, in which the dominated emission of green luminescence Bi2ZnB2O7:Tb3+ attributed to the transition D-5(4) -> F-7(5) is centered at 546 nm. The dependence of the emission intensity on the Bi2ZnB2O7:Tb3+ concentration for the Bi2-xTbxZnB2O7 (0.01 <= x <= 0.15) was studied and observed that the optimum concentration of Tb3+ in phosphor was 13 mol% for the highest emission intensity at 546 nm.
