摘要：

The light absorption of Cr3+ – doped diopside CaMgSi2O6 and spinel ZnGaAlO4 was measured spectrophotometrically. Two absorption bands corresponding to the electron transition: 4A2g → 4T2g (low frequency band) and 4A2g → 4T1g (high frequency band) were obtained. Generally, the value of the estimated ligand field parameters Δ and B showed that the CrO bond in the studied two structures is of different character. Copyright © 1979 Verlag GmbH & Co.
