Abstract
Sm3+ doped Strontium tin phosphate (SrSn(PO4)2) nanopowder was synthesized using the Solid State Reaction (SSR) method, a well-known commercial technology for device applications. The synthesized nanopowder was characterized by using Powdered X-Ray Diffraction (P-XRD), Field Emission Scanning Electron Microscopy (FESEM) with Energy Dispersive X-ray Spectroscopy (EDS), Fourier Transform Infrared Spectroscopy (FT-IR), Photoluminescence (PL) and Photometric measurements. The average crystallite size of the prepared nanopowder was estimated by XRD using Debye- Scherer’s equation which is around18 nm. FESEM images show the non-uniformly distributed biscuit-like nano-flakes morphology of the prepared nanopowder. FT-IR analysis confirms the existence of phosphate group ions in the sample. PL spectra recorded for the synthesized nanopowder under 401 nm excitation showed three emission bands with the transition at 601 nm and the highest intensity in the Orange region. Photometric parameters such as Colour Rendering Index (CRI), Colour Correlated Temperature (CCT) and Colour purity of the synthesized nanopowder were also measured and. The prepared nanopowder has CRI of 54% with CCT 2017K and colour purity 97.8% which is an excellent material for LEDs and luminescent devices application.
