A simple method for preparing uniform amorphous films of mixed metal halides by means of two-source evaporation

摘要

Two-source evaporation of metal halides onto cooled substrates provides a simple method for achieving uniform amorphous networks of solid solution with any composition ratio, yielding film samples. We exemplify its novel use for in situ monitoring of cluster or nanocrystal formation in the films. The method may be applicable to exploring new films heavily doped with clusters or nanocrystals in a controlled manner. [References: 12]
