Orthorhombic Site Symmetry of Cr³⁺ in ZnNH₄PO₄ 6H₂O Crystals

Spectroscopic investigations of Cr³⁺ 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 Cr³⁺ in ZAPH is attributed to orthorhombic distortion.

Keywords: Chromium, orthorombic symmetry, optical absorption spectra, Zinc Ammonium phosphate hexahydrate (ZAPH)
