Temperature dependence of absorption and radiative lifetime of Cr³⁺doped Na₄Ge₉O₂₀ crystals

Abstract:	Absorption spectra, oscillator strength, radiative lifetime of R-line in Na4Ge9O20: Cr3+ were investigatoed in the temperature range of 10K and 300K. The measured temperature dependence of B-line was explained by a theoretical model which supposed that the population in excited states abode by Boltzmann distribution. A new method for determining positions of Cr3+ in complex crystals has been developed.
