Yes, most of CBD grown Bi2S3 films are amorphous or nanocrystalline due to the small growth temperatures which lacks in to driving energy required to form bigger crystallites. So its advisable to anneal the samples, but not above 200 C after which sulfur starts evaporating. It needs to be done in inert or vacuum environment.

I have prepared some Bi2S3 films by CBD, but the crystalline grains in the films are small. What's the problem of your deposition and what do you expect for the Bi2S3 films?

same is the problem with me.Films are amorphous or micro crystalline and I want to deposit pure single phase crystals for use in solar cells.
