عنوان انگلیسی Structural, Optical, and Luminescence Studies of Sm2O3-Doped Cd2Sr(PO4)2 Nanopowder
چکیده انگلیسی مقاله The motive of the present work is to study the structural, optical properties of Cadmium Strontium Phosphate nanopowder (CSP) prepared by Solid State Reaction(SSR)method, a well-known commercial and conventional synthesis technology to produce nanopowders. To study the nature of the prepared samples various characterization techniques like P-XRD-Powder X-Ray Diffraction studies, SEM-Scanning Electron Microscopy with EDS-Energy-Dispersive X-ray Spectroscopy, DRS-Diffuse Reflectance Spectroscopy, FT-IR-Fourier Transform Infrared Spectroscopy and PL-Photo Luminescence studies were adapted. From P-XRD, the average crystallite size is found in the order of 15 nm. SEM micrographs reveal non-uniform biscuit shaped flakes for the prepared sample. From DRS study, the estimated band gap value of the prepared nanopowder is 5.3 eV. FT-IR study confirms the presence of ions related to phosphate group in the prepared nanopowder. From PL studies the prepared sample exhibits intense emission at 596 nm for an excitation wavelength of 401 nm. The values of CP-Color Purity, CRI-Color Rendering Index and CCT- Color Correlated Temperature are also calculated.
