Optical Properties of Anatase and Rutile TiO2:Cr3+ Powders

Trinh Thi Loan*, Nguyen Ngoc Long

Abstract: Anatase TiO2 powders doped with 0.5, 1.0, 4.0 and 10 mol% Cr3+ have been prepared by hydrothermal method. The Cr3+ concentration and annealing effects on crystalline structure, absorption and photoluminescent spectra of the synthesized samples have been investigated. The band gap energy of anatase and rutile TiO2:Cr3+ powders with ...
