要約

Using the superposition model, the crystal field and zero-field splitting parameters of Cr³⁺ doped cassiterite (tin oxide), SnO₂ single crystals are computed. For calculations, the appropriate locations for Cr³⁺ ions in SnO₂ with distortion are taken into account. The experimental values and the zero-field splitting parameters in theory with local distortion agree fairly well. Using the Crystal Field Analysis Program and crystal field parameters, the optical energy bands for Cr³⁺ in SnO₂ are calculated. The findings indicate that in SnO₂ single crystals, one of the Sn⁴⁺ ions is replaced by Cr³⁺ ions.
