quenching of luminescence

With the Ba 2+ substitution for the Ca 2+ or Sr 2+ into the crystall, the luminescence properties of Eu 2+ has changed: the emission peak lowered and the thermal quenching temperature increased.

当用Ba2＋离子代替Ca2＋或Sr2＋离子进入晶体时，Eu2＋离子的发光特性发生改变：发射峰的峰值降低，热猝灭的温度升高。并采用位型坐标理论给予解释。

This paper briefly introduced the mechanism of charge transfer luminescence in scintillators containing Yb3+ ions, and the host effect on the thermal and concentrations quenching.

本文简要介绍了掺Yb3+闪烁晶体的电荷迁移发光的机理以及基质晶体对温度猝灭与浓度猝灭的影响。

The luminescence intensity and chromaticity of the Eu3+ reached its highest in case of mixing Gd3+, 21mol%, into Thenardite ( Na2SO4: Eu) crystal lattices, and Concentration quenching effect ultimately occurred.

当Gd3+以21mol%掺入到无水芒硝（Na2SO4：Eu）晶格中时，可以达到Eu3+的最强发光强度和最佳色纯度，最终出现浓度淬灭现象。

the intensity is related to the extent of oxygen quenching of luminescence.

强度有关的范围内氧猝灭发光。

Meanwhile, luminescence quenching and band narrowing of NX line have been observed under pressure.

同时, 观察到压力下N_ 带发光猝灭及谱带窄化现象.
