Eu, Er, Yb-Er, and Dy-doped phosphate glasses were prepared by a wet-route processing of chemical precursors followed by melt-quenching and annealing. XRD measurements highlighted the amorphous nature of the investigated glasses. UV-Vis absorption spectra revealed peaks specific to f-f electronic transitions of the doping ions whereas FTIR and Raman spectroscopy proved the vitreous network forming role of phosphorous pentoxide. Luminescence spectra in the Vis domain, at RT, showed emission bands characteristic to the ion transitions from the excited states to the ground state. The luminescence spectra collected in the 25-160°C range exhibited a decrease of the emission intensity with temperature rise. In the case of Eu and Dy-doped glasses a relatively small decrease of the emission intensity with temperature is observed by comparison with Er and, respectively, Yb-Er-doped glass where a significant change of the emission intensity is noticed, which recommends the latter as promising candidate for sensing devices.

Eu，Er，Yb-Er和Dy掺杂的磷酸盐玻璃是通过化学前体的湿法加工，随后的熔融淬火和退火制备的。XRD测量结果突出显示了所研究眼镜的无定形性质。UV-Vis吸收光谱显示出特定于掺杂离子的ff电子跃迁的峰，而FTIR和拉曼光谱证明了五氧化二磷的玻璃网络形成作用。在室温下，Vis域的发光光谱显示出从激发态到基态的离子跃迁所特有的发射带。在25-160℃范围内收集的发光光谱显示出随着温度升高发光强度降低。与Eu和Dy相比，在掺Eu和Dy的玻璃中，发射强度随温度的降低相对较小。
