英文摘要	Erbium-doped hydrogenated amorphous silicon suboxide films containing silicon clusters (a-siox:h) were prepared. the samples exhibited photoluminescence (pl) peaks at around 750nm and 1.54 mu m, which could be assigned to the electron-hole recombination in silicon clusters and the intra-4f transition in er3+, respectively. we compared annealing behaviors of si clusters and er3+ emission and found that si clusters emission depends strongly upon crystallinity of si clusters, whereas er3+ emission is not sensitive to whether it is si nanocrystals (nc-si) or amorphous si (a-si) clusters. the erbium-doped a-siox:h films containing either a-si clusters or nc-si have the same kind of er3+ -emitting centers. based on these results, it is concluded that a-si clusters can play the same role on er3+ excitation as nc-si.
