Orthorhombic Site Symmetry of Cr3+ in ZnNH4PO4 6H2O Crystals

Spectroscopic investigations of Cr 3+ doped ZAPH are carried out. From the nature of optical absorption bands and their splittings at the liquid nitrogen temperature, the site symmetry of the Cr 3+ in ZAPH is attributed to orthorhombic distortion.
