Characterization of newly synthesized Strontium Cerium Niobate nanophosphor

Niobium based phosphor have been found very useful for various industrial and technological applications. Nano Strontium Cerium Niobate (SCN) has been synthesized for the first time by the hydrothermal method. The main advantage of the hydrothermal method is to reduce the higher synthesis temperatures and to obtain less agglomeration of the nanocrystals by using different solvents. The structural evolutions and morphological characteristics of the Strontium Cerium Niobate were investigated by X-ray diffractometry, showing high crystallinity and monoclinic structure of the phosphor. XRD confirms that the specimen has single perovskite phase. Photoluminescence emission spectrum shows an intense peak at 397 nm when excited at 316 nm. Fourier transform infrared spectrum (FTIR) has been done to confirm the different bonds that are responsible for the emission centers. -- Highlights: • Our group is the first to synthesize this particular Strontium Cerium Niobate (SCN) nanophosphor using low temperature hydrothermal method. • SEM image shows that SCN has cotton flower shape while FTIR shows SCN nanosize perovskite structure has edge-connected Nb–O octahedral. • Photoluminescence shows that SCN samples yields intense emission peaks at 396 nm and two shoulder peaks at 451 nm and at 469 nm
