摘 要：The present paper summarises the synthesis of La3+doped zinc oxide nanoparticles using Aloe vera gel by solution combustion method and the characterization using a powder X-ray diffractometer（PXRD）,a transmission electron microscope（TEM）,an X-ray photometric spectrometer（XPS）,a Raman spectrometer and their applications in optical devices and latent fingerprinting.PXRD pattern confirms the crystallite size of La3+doped ZnO varies from 13 to 20 nm.Crystallite size varies inversely with doping concentration.Photoluminescence properties are found to be the maximum for 2 mol% doping concentration.PL spectra extends the use of ZnO:La3+nanoparticles in blue green LED.These nanoparticles also have superior property as a fluorescent labels in fingerprints.
