Optical absorption intensity analysis using Judd-Ofelt theory and photoluminescence investigation for red-emitting Eu3+: TiO2 nanoparticles

摘要

Nanoparticles of Eu3+ doped TiO2 have been synthesized by the hydrothermal technique. Structural, morphological, and luminescence characteristics of the nanophosphors were examined in detail. The powder X-ray diffraction pattern reveals that below 9 mol% concentration of Eu3+ doped TiO2, all samples show the anatase phase with tetragonal structure.
