摘要：

CdSiO3:Ho3+ nanophosphor have been synthesized by solution combustion technique. The powders are well characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), Fourier Transform Infra Red spectroscopy (FTIR) and UV-visible spectroscopy. The average particle size is estimated from Scherrer's method and Williamson-Hall (W-H) plots and found to be in the range 15-40 nm. Scanning electron microscope (SEM) pictures showed highly porous, fluffy and many agglomerated particles. The optical band gap (E-g) of the phosphor is estimated from Wood and Tauc relation and is found to be 5.6 eV. A well intense characteristic emission peak at 543 nm is recorded for 331 nm excitation.
