Vapor Phase Synthesis and Optic Properties of MoO2 Micro/nanosheet

MoO2 micro/nanosheets were synthesized by vapor-deposit process and characterized by XRD, SEM, TEM, UV-Vis and photoluminescence (PL) photometer. The results show that MoO2 micro/nanosheet is rectangle, and the length and width range from several to dozens of micrometers and about 200 nm thick. The MoO2 micro/nanosheets have absorbance peaks between 200–300 nm, and three fluorescent excitations at 304.6, 343.4 and 359.6 nm. The synthesis mechanism of MoO2 micro/nanosheets was discussed based on the experimental results and the thermodynamic computation.
