    It has been shown that [Er-O] clusters play the role of photoluminescence centers in films of amorphous hydrogenated silicon a-Si(H) doped with oxygen and erbium. The local symmetry of Er ions in clusters is the same as that in ErO. A decrease in the cluster size and an increase in the particle...
