Prepare raw materials: cesium tungstate powder, organic solvents (such as ethanol, acetone, etc.), surfactants (such as sodium lauryl sulfate, etc.).
Add the cesium tungstate powder into the organic solvent and stir evenly to make it fully dispersed.
While stirring, add an appropriate amount of surfactant and continue stirring to make the dispersion more uniform.
Sonicate the mixture to make it more finely dispersed.
Filter and centrifuge the dispersion to remove impurities and insoluble substances to obtain pure cesium tungstate dispersion.
