Niobium*oxide nanoparticles & quantum dot and Vanadium quantum dot were synthesized by sol-gel method. Niobium pentoxide was solubilized with hydrofluoric acid in order to get niobic acid precipitate by using ammonia solution. To reduce the particle size, the niobic acid was treated with hydrofluoric acid. Vanadium pentoxide was solubilized with hydrogen peroxide and hydrothermally treated to get Vanadium oxide quantum dot, but instead of getting quantum dot we got layered structure of vanadium oxide. The samples were characterized by TEM, FE-SEM, SEM XRD and FTIR. From these characterization it was observed that the average size of the niobium oxide nanoparticles was found to be 30nm. The size, shape, morphology and surface area of the nanoparticles are highly dependent upon the amount of ammonia solution used for their synthesis, temperature and duration of hydrothermal treatment that they are subjected to. The cell imaging of niobium oxide nanoparticle and diluted vanadium oxide ultra-sonicated gel was done by confocal microscopy which showed fluorescence. Supercapacitor was also developed by niobium oxide nanoparticle.
