Abstract The optical properties of Dy3+-doped lithium aluminoborate glass are investigated. Sample series of varying modifier-to-former ratio and different Dy3+ concentration are analysed for their optical absorption, quantum efficiency, photoluminescence yield, and chromaticity. The samples show a luminescence quenching upon increasing the Dy3+ concentration, though the optical absorption increases linearly. Changing the modifier-to-former ratio in favour of the network former leads to an increase in luminescence yield. For all samples, the photoluminescence spectra are dominated by two emission bands in the visible spectral range, namely at 483 nm and 575 nm. The relative contribution of these bands to the total luminescence changes with the modifier-to-former ratio as well as the Dy3+ concentration. The colour impression of the samples changes accordingly.

Dy3+ 掺杂的铝硼酸锂玻璃的色移

摘要 研究了Dy3+掺杂铝硼酸锂玻璃的光学性能。分析了不同改性剂与形成剂比率和不同 Dy3+ 浓度的样品系列的光吸收、量子效率、光致发光产率和色度。尽管光吸收线性增加，但样品在 Dy3+ 浓度增加时显示出发光猝灭。改变改性剂与形成剂的比例有利于网络形成剂导致发光产率增加。对于所有样品，光致发光光谱由可见光谱范围内的两个发射带主导，即 483 nm 和 575 nm。这些带对总发光的相对贡献随着改性剂与形成剂的比率以及 Dy3+ 浓度而变化。
