Özet

An EPR and optical studies of VO2+ doped potassium dihydrogen citrate (PDHC) single crystals have been carried out at room temperature. It crystallizes in triclinic symmetry with the unit cell dimensions: a = 11.343 angstrom, b = 13.078 angstrom, c = 6.272 angstrom, alpha = 89.79 degrees, beta = 94.36 degrees, gamma = 104.2 degrees. The angular variation of EPR spectra have shown that two different VO2+ complexes are located in different chemical environments and each environment contains one magnetically VO2+ site occupying substitutional position in the lattice and show very high angular dependence.
