Abstract

The photoluminescence properties of Cr-doped PLZT-9/65/35 (Pb0.95La0.09Zr0.65Ti0.35O3) have been studied. The fluorescence spectra consist of two inhomogeneously broadened narrow bands centred at similar to 734 and 740 nm and a broadband emission with a maximum at similar to 1000 nm. The two high energy bands have been assigned to the E-2(T-2(1)) -> (4)A(2) transition of two Cr3+ defect centres in octahedral site with high/ intermediate crystal field strength whereas the near infrared emission is tentatively assigned to the overlapping of the broadband emission of the Cr3+ ions defect centre's T-4(2) -> (4)A(2) transition and the emission of the Cr5+ ions' E-2 -> T-2(2) transition.
