Sol-Gel Synthesis & Photoluminescence of Multiple Layer LaPO₄ Nanostructure Thin Films

Abstract:

The present paper reports on the structural properties of Lanthanum Phosphate (LaPO4) nanostructure film in term of its surface morphology. In this study, the LaPO4 samples were prepared by sol-gel spin coating method with different layers. Photoluminescent (PL) properties of the samples were investigated using FluoroMax-4 Spectrofluorometer - Horiba Scientific at room temperature with excitation spectra 254 nm. While its physical structural properties was investigated using atomic force microscopy (AFM-XE100).
