Glasses from two varieties of (LiF-B₂O₃) and (LiF-P₂O₅) systems with equal 50 mol % for each partner together with samples doped with 1 or 2% Bi₂O₃ were synthesized by melting–annealing mechanism. Multiple optical, FTIR and photoluminescence spectral measurements were carried out. Optical spectra of Bi₂O₃—doped glasses exhibit UV-near visible peaks owing to the specific absorption of Bi³⁺ ions. FTIR spectra elucidate the presence of characteristic vibrational bands from (LiF-B₂O₃) glass due to (BO₃) and (BO₃F) groups beside (LiF₄) groups while the fluorophosphate glasses (LiF-P₂O₅) show vibrations due to PO₄ and (PO₃F) groups and also the possible sharing of (LiF₄) groups. Photoluminescence spectral data reveal extended emission from about 375 to 700 nm and is more prominent in (LiF-B₂O₃) system than (LiF-P₂O₅) system. The thermal expansion data reveal similar behavior and the derived transition and softening temperatures are slightly lower in (LiF-P₂O₅) glasses than (LiF-B₂O₃) glasses.

通过熔融-退火法合成了来自两种不同的 (LiF-B ₂ O ₃ ) 和 (LiF-P ₂ O ₅ ) 系统的玻璃，其中每个伙伴的浓度为 50 mol %，以及掺杂有 1 % 或 2 % Bi ₂ O ₃的样品机制。进行了多次光学、FTIR 和光致发光光谱测量。由于 Bi ³⁺离子的特定吸收，Bi ₂ O ₃掺杂玻璃的光谱显示出近紫外可见峰。FTIR 光谱阐明了 (LiF-B ₂ O ₃ ) 玻璃由于 (BO ₃ ) 和 (BO ₃F) 基团位于 (LiF ₄ ) 基团旁边，而氟磷酸盐玻璃 (LiF-P ₂ O ₅ ) 显示出由于 PO ₄和 (PO ₃ F) 基团以及 (LiF ₄ ) 基团可能共享引起的振动。_{光致发光光谱数据揭示了从约 375 到 700 nm 的扩展发射，并且在（LiF-B 2} O ₃）系统中比（LiF-P ₂ O ₅ ）系统更突出。_{热膨胀数据揭示了类似的行为，并且 (LiF-P 2} O ₅ ) 玻璃中得出的转变温度和软化温度略低于(LiF-B ₂ O ₃） 眼镜。
