Synthesis by Sol–Gel Method and Characterization of CaAlO: Mn, Dy Nanoparticles

Abstract

Dy and Mn doped Calcium Aluminate nanoparticles were synthesized by using Sol-gel method. Heat treated material was characterized by X-ray diffraction(XRD), optical study of photoluminescence (PL) emission spectra, morphological study of scanning electron microscopy (SEM) combined with X-ray analysis. The Dy and Mn doped phosphor exhibits emission at the excitation of the material with 380 nm wavelength generates a strong emission at 480 nm. Besides this, subsidiary maxima at 417, 422 nm wavelength in violet region and 620 nm in red region.
