The refractive indices of 0.9Pb(Zn 1/3 Nb 2/3 )O 3 ‐0.1PbTiO 3 single crystal at different wavelengths have been measured by the minimum deviation method at room temperature, and their dispersion equations are obtained. The parameters connected to the energy band structure are obtained by fitting single‐oscillator dispersion equation. Despersion energies are found to take on covalent crystal values.
