A series of europium (Eu3+) doped SrO + ZnO + PbO + P2O5 glasses with varied ZnO and PbO compositions have been prepared by melt quenching method. The structural and optical properties of the samples are analysed by XRD, FTIR, absorption, optical band gap energy, excitation, phonon sideband (PSB) spectrum, luminescence emission, decay profile and CIE chromaticity coordinates. The most intense emission is found at 611 nm (red) corresponding to 5D07F2 transition. Using the luminescence emission spectra, the branching ratio (βm), effective bandwidth (Δλeff) and emission intensity ratio (R) have been calculated. The decay profile of the 5D0 excited state is fitted with a single exponential function and thereby lifetime is evaluated. The high colour purity of 97.4% in the red region is estimated for the EuSr30ZnPbP glass. The luminescence properties indicate that the present glasses could be used for red laser materials and optical display devices.

ZnO和PbO组成不同的掺((Eu 3+)锶磷酸锌铅玻璃的光谱研究

通过熔体淬火法制备了一系列掺有不同的ZnO和PbO的of(Eu 3+)掺杂的SrO + ZnO + PbO + P 2 O 5玻璃。通过XRD,FTIR,吸收,光学带隙能量,激发,声子边带(PSB)光谱,发光发射,衰减曲线和CIE色度坐标来分析样品的结构和光学性质。在611 nm(红色)处发现了最强的发射,对应于5 D 07 F 2跃迁。使用发光的发射光谱,分支比(β),有效带宽(Δ λ EFF)和发射强度比(R)已计算出来。5 D 0激发态的衰减曲线与单个指数函数拟合,从而评估了寿命。EuSr30ZnPbP玻璃在红色区域的色纯度高达97.4%。发光性能表明本发明的玻璃可用于红色激光材料和光学显示装置。
