Abstract
The quantum‐mechanical single‐configurational‐coordinate model is used to interpret Y2O2S:Eu+3 and La2O2S:Eu+3 7F→charge‐transfer state (CTS) absorption, 5Di→5Di−1 one‐step and 5D→CTS→5D two‐step quenchings, and CTS→5Di feeding fractions. The preferred fit requires unequal force constants and a small downshifting of the CTS parabola with increasing temperature.Keywords
