Best Solvent for ZnO Powder Solution and Drying Method for Glass Substrate Drop Casting

The discussion addresses the preparation of a zinc oxide (ZnO) powder solution suitable for drop casting onto glass substrates. No direct solvent recommendations or drying protocols were provided. Participants suggest consulting scientific literature, such as research papers and datasheets, for detailed methodologies on dissolving ZnO powder and optimal drying techniques. It is implied that heating the substrate post-drop casting may be considered, but no consensus or specific temperature guidelines are given. The emphasis is on leveraging academic resources and official component datasheets to determine appropriate solvents and drying methods for ZnO thin film fabrication via drop casting.
