Description

Photoionization transitions of chromium ions in CdxZn1-xSe:Cr bulk crystals (0≤x≤0.3) were studied in wide temperature range (4-300 K). By monitoring changes of the Cr1+ electron spin resonance signal under external illumination, we are able to determine energies of Cr2+ => Cr1++hVB transition in different CdxZn1-xSe host crystals. At low temperature we observe metastable population of photo-excited Cr1+ centres. (copyright 2004 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)
