| Abstract: | A method for the synthesis of vanadium dioxide (VO2) nanoparticles in nanoporous silicate glass matrices with a pore size of 17 and 7 nm has been developed. According to this, vanadium pentoxide (V2O5) nanoparticles are initially grown in the pores, and then V2O5 is reduced to VO2 in hydrogen. The optical transmission spectra of 1-mm-thick VO2-modified glass samples have been measured. The temperature dependence of the transmission coefficient has been studied in the course of the semiconductor-metal phase transition in VO2 nanoparticles. |
