Abstract
New rare earth Strontium Cerium Niobate (SCN) was synthesized for the first time by hydrothermal method. The main advantage of the hydrothermal method is that to reduce the higher synthesis temperatures and to obtain less agglomeration of the nanocrystals by using different solvents. X-Ray Diffractometer shows high crystallinity and monoclinic structure of the strontium cerium niobate. Fig. 1 shows XRD measurement of Strontium Cerium Niobate Photoluminescence emission shows emission at 390nm when this SCN exited at 362nm. Fourier transform infrared spectrum has been done to confirm the different bonds that are responsible for the emission centres.
