Photoconductivity in LiNbO3 crystals codoped with MgO and Cr2O3

The photoconductivity of LiNbO3 crystals codoped with Cr2O3 and different concentrations of MgO from 0 up to 6 mol% is reported. The spectral excitation of photocurrent presents an intense band corresponding to the Cr3+ induced blue absorption edge, but illuminating at the 4 A 2->4 T 1 ionic tran...
