✦ Synopsis

Single crystals of Copper-doped Lithium sodium potassium sulphate were grown at room temperature. The optical absorption spectra were recorded at room and liquid-nitrogen temperatures. The observed absorption bands have been attributed to an ion of Cuz+ in tetragonal symmetry with 'B, as the ground state. A successful interpretation of all the observed bands have been made by taking into consideration spin-orbit coupling associated with a tetragonal field.

The crystal field parameters derived are Dq = 1045 cm-', Ds = 1352 cm-' and Dt = 457 cm-'.
