Sodium Fluoride Evaporation Materials Description
Sodium fluoride is a compound of sodium and fluorine that forms a colourless crystalline solid with a cubic crystal structure. When used as an evaporation material, it exhibits several properties that make it suitable for thin film deposition.
- High Melting Point: Sodium fluoride has a melting point of approximately 993 °C (1 819 °F). This property enables it to tolerate the heat generated during deposition without sublimating prematurely.
- Stable Vapour Pressure: At elevated temperatures, sodium fluoride maintains a stable vapour pressure. This stability ensures a steady and controlled evaporation rate during deposition, thereby contributing to the uniformity of the thin films.
- Reactive Nature: Sodium fluoride reacts with moisture. Users must handle these evaporation materials in controlled environments to avoid contamination or reactions with ambient humidity.
- Broad Transmission Range: Thin films of sodium fluoride show optical transparency over a wide spectral range from ultraviolet (UV) to infrared (IR). This feature makes them suitable for optical coatings, anti-reflective coatings and other applications that require precise control of light transmission.
