Abstract

Different concentrations of B2O3 in zinc–aluminum–sodium–phosphate (ZANP) glasses were synthesized by the conventional melt-quenching method and analyzed using X-ray diffraction (XRD), optical absorption, excitation, visible luminescence, decay lifetime, and chromaticity methods. The amorphous nature of the glasses was confirmed by the absence of sharp diffraction peaks in the XRD profile. In the visible emission spectra blue, yellow, and red bands were observed and the intensity of the yellow band was superior. Furthermore, the samples show a luminescence quenching beyond 20 mol.% of B2O3 concentration. The decay lifetime of 4F9/2 of Dy3+ ions was found to be maximal in ZANP Dy0.5:20B2O3 glass.

B2O3 对掺杂 Dy3+ 离子的锌铝磷酸钠玻璃光学特性的影响
采用传统的熔淬法合成了不同浓度的磷酸锌铝钠(ZANP)玻璃中的 B2O3,并使用 X 射线衍射(XRD)、光吸收、激发、可见光发光、衰减寿命和色度方法对其进行了分析。X 射线衍射曲线中没有尖锐的衍射峰,这证实了玻璃的无定形性质。在可见光发射光谱中观察到蓝色、黄色和红色条带,其中黄色条带的强度更高。此外,当 B2O3 浓度超过 20 摩尔/% 时,样品会出现发光淬灭现象。在 ZANP Dy0.5:20B2O3 玻璃中,Dy3+ 离子 4F9/2 的衰变寿命达到最大。
