Photoluminescence in nanocrystalline MMoO4 (M = Ca, Ba) synthesized by a polymerized complex method

Nanocrystalline MMoO4 (M = Ca, Ba) were successfully synthesized at low temperatures via a polymerized complex route and room temperature photoluminescent properties were investigated in detail. Prepared nanocrystalline MMoO4 (M = Ca, Ba) showed primarily dispersed and homogeneous morphology with particle size of 20-40 nm. The photoluminescent spectra were decomposed to several individual Gaussian components in green and blue wavelength range. These photoluminescent features could be interpreted by Jahn-Teller splitting effect on [MoO(4,^2-)] tetrahedron of the nanocrystalline MMoO4 (M = Ca, Ba).
