Abstract
This paper describes experimental studies of the distribution of crystal field sites occupied by Cr3+ ions in different glasses. The effects of this site-to-site disorder on the optical band shape of 4T2 ↔ 4A2 and 2E ↔ 4A2 transitio ns and their temperature dependences are calculated, on the assumption that the disorder distribution function is a Gaussian and compared with experimental results.
