Abstract

Alkali metal ions (Li+, Na+ & K+) co-doped ZnTiO3:Eu3+ red emitting nano-phosphors series were prepared by combustion synthesis method. The crystal structure & surface morphology of the phosphors was analyzed by using X-ray diffraction (XRD) and Scanning electron microscopy (SEM) technique. The XRD results show the hexagonal phase of ZnTiO3 with space group R-3:R. From the SEM results, it was observed that the phosphors had very small particle size ranging from 10-30nm and the average size of the ZnTiO3 crystal is 30±5nm. Photoluminescence study showed that under the excitation of UV (393 nm) or blue light (464 nm) , the obtained products emitted characteristic red emissions of Eu3+ at 615 nm for 5D0 → 7F2 transition which proved that activator Eu3+ ion had successfully entered the host lattice of ZnTiO3. The red emission intensity was significantly enhanced by introducing alkali metal ions as co-dopants. A remarkable increase in the photoluminescence intensity is found by co-doping with Li+ ions in ZnTiO3:Eu3+ lattices due to the reduction of environment symmetry around Eu3+ ions which strengthen the electric dipole transition.
