Preparation and Characterization of Lanthanum Doped Calcium Aluminate Nanophosphor (CaAl2O4: La) by Sol-Gel MethodBy M Freeda, G. Suresh
Abstract: Abstract Lanthanum doped calcium aluminate nanophosphor (CaAl2O4: La) was prepared by sol-gel method. Characterizations such as XRD, SEM, EDAX and PL were done. Monoclinic structure was confirmed by the XRD analysis; the particle size was found to be 27 nm and is determined by (Williamson and Hall plot) W-H plot method. It shows that the particles were of small granular structure, and were interlinked with each other, lead to the …

A Simple Sol–Gel Route for the Synthesis and Characterization of Tm-Doped CaAl2O4 NanophosphorBy M Freeda, G. Suresh
Abstract: Calcium Aluminate nanophosphor doped with Thulium (CaAl2O4: Tm) was synthesized by simple sol–gel route. The obtained nanophosphor was characterized by X-ray diffraction technique (XRD). The surface morphology was determined by scanning electron microscopy (SEM). Also photoluminescence spectra (PL), and thermogravimetric analysis/differential scanning calorimetry (TGA/DSC) characterization were done. The XRD revealed the formation of monoclinic structure and the particle size was determined by Scherrer formula. It showed that the particles were …
