Abstract

The TiO2 nanoparticles doped with Ho3+ and Yb3+ ions were synthesized by sol gel method. The structure of the samples were characterized by XRD, TEM and by thermo gravimetric analysis. The average particle size of the TiO2 range from 7-10 nm (in diameter). The result obtained from TEM, XRD studies indicate that the rare earth ions were positioned in low phonon glass. The photoluminescence (PL) and upconversion (UC) properties of Ho3+ in various concentrations of TiO2 nanoparticles have been investigated. The PL and UC luminescence depends on particle size and crystal structure and we also observed that the emission of Ho3+ in silica xerogel was significantly depends on the amount of TiO2 nanoparticles.
