Lowering the transition temperature of VO2(M) that can switch the near infrared (NIR) transmittance by phase transition is a key factor for the practical applications to energy-saving smart windows of this material. Tungsten doping into VO2(M) is known to be the most effective method for this purpose but the doping also seriously decreases the transition sharpness and NIR switching efficiency dramatically decreases. Previously we reported that the codoping of W/Mg enhanced the transition sharpness as well as lowering the transition temperature. We also showed that the doping of Nb was as much effective as W-doping for lowering the transition temperature differently from the previously known studies as long as the Nb-doped VO2(M) was prepared by a hydrothermal and post-thermal transformation method. In this study we are going to show the synergistic effect of codoping of Nb and Mo into VO2(M). We have synthesized the Nb/Mo-codoped VO2(M) by a hydrothermal and post-thermal transformation method and prepared its thin films by a wet-coating method from its solvent-dispersed coating solution. The transition characteristics of the codoped VO2(M) nanoparticles and their thin films was investigated with comparison of single Nb-doped ones.
