Photochromic coating by vacuum deposition
Photochronic thin films have been obtained by the simultaneous deposition of silicon monoxide, lead silicate, aluminum chloride and copper-sensitized silver halide, followed by a heat treatment in the dark and in air at 100°–200°C for several hours. The growth of silver halide microcrystals in the f...

| Summary: | Photochronic thin films have been obtained by the simultaneous deposition of silicon monoxide, lead silicate, aluminum chloride and copper-sensitized silver halide, followed by a heat treatment in the dark and in air at 100°–200°C for several hours.
The growth of silver halide microcrystals in the film is explained by a simple diffusion-limited process. The fading process can be described by a second order chemical reaction, which has been applied to a type of photochromic glass containing silver halide microcrystals in the glass matrix. The half-fading and half-darkening time of typical films were 10–20 min and 5–20 min, respectively. |
