Characterization of MoO<sub>3</sub> Solution Prepared Using Bath Deposition

Abstract

MoO3 film is successfully prepared by water bath heating method. The existence of Mo element in the MoO3 solution is determined by infrared test. The characteristic peak of Mo element roughly appears within the range from 500 cm–1 to 700 cm–1.Then the MoO3 peak is found appearing at the location of the 30°–40° using XRD, which proves the existence of MoO3 in the solution. SEM observations indicate that the MoO3 film is smooth as the reaction continues for 4 h. Finally, the results of light absorption test show that MoO3 film has a good absorbency.
