Absorption and fluorescence spectra and fluorescence lifetime measurements are presented for Ce 3+ :Er 3+ :Yb 3+ :YVO 4 crystals and compared to the corresponding data for Er 3+ :Yb 3+ :YVO 4 crystals. These results show that doping with Ce 3+ ions reduces the lifetime of the 4 I 11/2 state of Er 3+

YVO 4 single crystals doped with Ce 3+ , Er 3+ and Yb 3+ ions were grown by the Czochralsski technology. The luminescence properties of Er 3+ /Yb 3+ :YVO 4 single crystals with different concentration of Ce 3+ were studied, and the energy transfer mechanism between Er 3+ , Yb 3+ and Ce 3+ was discus
Electron paramagnetic resonance studies of molybdenyi doped NH4Br crystals were made at room temperature. The resonance due to even isotopes of MO and the hyperfinc interaction due to g5\*g7hfo is observed. The angular variation of the spectrum is studied in the crystallographic (001) plane. The sym
The EPR of Gd3' in PrF3 has been observed to be consistent with the C2v symmetry of the fad crystallirle field, but the linewidths show an unusual variation along a fixed direction. The orientation of the Y axis of the spectrum convincingly supports the C& structure for the crystat and not the Dfd s
