In the optical energy gap, visible and near-IR emission of halide phosphate glasses with a composition of 40PO-30ZnO-20LiCl-10BaF in mol% doped with 3.5 × 10 ppm PrO, referred to as PZLBPr, were synthesized. The UV-VIS-NIR and spectroscopic properties of these glasses were also predicted. The current glasses had broadband emission photoluminescence covering a wavelength range of 1250 to 1700 nm when excited at 455 nm. These bands for near-infrared emission luminescence relate to the transitions G → H, D → G, and H → F, F in the optical telecommunication window. The significant PL emission wideband was caused by the radiative transition from Pr: D to G. At 445 nm excitation, these glasses exhibited emission bands that corresponded to blue/reddish orange spectral ranges in visible ranges. The prepared glass has a high lasing quality factor (Ω/Ω = 0.9), high optical energy (4.72 eV), and quantum efficiency = 87.3% with FWHM = 156 nm of transition emission from the D → G level. As a result, broadband near infrared optical amplifiers can be fabricated from the prepared glasses.
合成了摩尔百分比组成为40PO-30ZnO-20LiCl-10BaF且掺杂3.5×10 ppm PrO（称为PZLBPr）的卤化物磷酸盐玻璃，研究了其在光能隙中的可见和近红外发射。还预测了这些玻璃的紫外-可见-近红外和光谱特性。当在455 nm激发时，当前的玻璃具有覆盖1250至1700 nm波长范围的宽带发射光致发光。这些近红外发射发光带与光通信窗口中的G→H、D→G和H→F、F跃迁有关。显著的PL发射宽带是由Pr：D到G的辐射跃迁引起的。在445 nm激发下，这些玻璃在可见范围内表现出对应于蓝/红橙色光谱范围的发射带。所制备的玻璃具有高激射品质因数（Ω/Ω = 0.9）、高光学能（4.72 eV）以及87.3%的量子效率，D→G能级跃迁发射的半高宽为156 nm。因此，可以用所制备的玻璃制造宽带近红外光放大器。
