Violet tungsten oxide nanoparticles for new energy efficient building glass can be synthesized by a solvothermal method by changing the solvent type of the precursor, the reaction temperature and time of the solution, and the molar concentration of the solution.

In terms of performance, experts conducted a test on the adsorption properties of Rhodamine B and the UV-Vis-NIR absorption properties of the prepared violet tungsten oxide (W18O49). The results showed that W18O49 obtained at the reaction temperature of 180°C, reaction time of 12h and solution molar concentration of 25mM had the best adsorption performance when the selected alcohol solvent was isopropanol. And the W18O49 nano particles obtained by the experiment all have good near-infrared absorption properties. At the same time, the nitrogen adsorption BET test of the obtained W18O49 powder proved that these nano particles have a large specific surface area and a relatively uniform pore size distribution.
