Spectroscopy and Laser Applications

Results of EPR and optical studies of vanadyl ion (VO2+) doped in single crystals of sodium formate are reported. Impurity sites in the unit cell and the molecular structure of the vanadyl complexes are discussed. The spin Hamiltonian parameters are determined. From optical and EPR data, crystal field parameters are calculated and discussed. Two complexes at substitutional sites at two different levels of doping have been identified.
