Tungsten oxide nanoparticles for near infrared shielding material can be obtained by a solvothermal method using ethanol as an alcohol solvent, a molar concentration of 15mM, a reaction time of 24 hours at a different temperature (160°C, 180°C, 200°C). The figure below shows the XRD spectrum of the synthesized tungsten oxide (WO3-X) product.

So, what effect does the reaction temperature have on the phase of the product? XRD diffraction analysis was performed on the prepared tungsten oxide powder. From the diffraction pattern, it can be seen that when he solvent in the precursor is ethanol, the molar concentration of the solution and the reaction time are fixed, the XRD diffraction spectrum of the product obtained by changing the reaction temperature is in agreement with the standard powder diffraction XRD pattern, which is the W18O49 phase. The reaction product was a pale blue or light blue powder.
