摘要

A red-emitting phosphor of Eu~3+-doped calcium-tellurium-zinc oxide, Ca_3Te_2(ZnO_4)_3, with a garnet-type structure was synthesized by high temperature solid-state reactions. This phosphor exhibited astrong red emission. The photoluminescence excitation spectrum showed that Ca_3Te_2(ZnO)4)_3:Eu~3+canbe effectively excited by UV-visible light. The property of long-wavelength excitation for this materialhas a benefit as a red phosphor in application of white light-emitting diodes. The colour coordinateswere calculated. The excitation and emission spectra and luminescence decay curves were obtainedusing a pulsed, tunable, narrowband dye laser. Crystallographic sites and charge compensationmechanism of Eu~3+ions were discussed. The emission line fromEu3+in intrinsic crystallographic site inthe lattice was located at 579.56 nm. The emission line from Eu3+ in another disturbed site, which iscreated by the defects created by the charge-compensation, was located at 580.88 nm. The disorderedcrystallographic sites of Eu~3+are benefit for their strong red luminescence corresponding to the~5D_0→~7F_2transition.
