| Abstract: | Mo-doped SnO2 nanocrystals were synthesized with SnCl4·5H2O and(NH4)6Mo7O24·4H2O as the raw materials,hydrolyzed,separated and calcinated.The synthesized products were characterized by XRD,TEM,diffuse reflectance spectrum and room-temperature photoluminescence(PL) spectrum.The result shows that there are SnO2 nanoparticles with the size of ca.2.5 nm.The photoluminescence of SnO2 is tested and found to have the emissions at 463,490 and 537 nm in visible region. |
