Application

Cesium chloride can be used:
  • To prepare Ga2S3-GeS2-CsCl glasses, which are transparent in the entire visible range.
  • To fabricate WO3 islands and network structures, which improves the light extraction efficiency of an OLED.
It can also be used to make solutions for the separation of RNA from DNA by density gradient centrifugation.
