Abstract: Thin films of lanthanum phosphate (LaPO₄) nanostructures were fabricated on quartz substrate using sol-gel spin coating method subsequent with drying and annealing process. Increase of annealing temperature will increase the intensity of diffraction peaks; reveal that the particle size and crystalline increase with temperature. A monoclinic structure was shown to be present in LaPO₄ thin films after first anneal at 200°C. The LaPO₄ nanostructures of average size 30-50 nm were observed with field emission scanning electron microscopy. While the crystallise size were measured with X-ray diffraction (XRD). The images of LaPO₄ nanostructure films show uniformity of samples with homogenously close-packed morphology.
