Han, Guang and Chen, Zhi-Gang and Zou, Yichao and Drennan, John and Zou, Jin (2014) Long wavelength emissions of Se4+-doped In2O 3 hierarchical nanostructures. Journal of Materials Chemistry C, 2 (32). pp. 6529-6535. ISSN 2050-7526

Abstract

Se4+-doped cubic-structured In2O3 hierarchical nanostructures have been synthesized by controllable thermal oxidation of In3Se4 nanostructures. The synthesized nanostructures preserve the original hierarchical morphology of In 3Se4 nanosheet-assembled nanostructures. Moreover, the In3Se4 single crystalline nanosheets can be transformed into Se4+-doped In2O3 polycrystalline structures consisting of interconnected nanoparticles. The photoluminescence property measurements show that the Se4+-doped In2O 3 hierarchical nanostructures have red light emissions centered at 630, 670, and 770 nm and near infrared emissions centered at 910 nm, which is ascribed to the Se4+ doping.
