| Abstract: | A multicomponent Stark structure corresponding to a 4I
13/2→4I
15/2 transition in the 4f
11 shell of Er3+ ions is observed in hydrogenated amorphous silicon (a-Si:H) subjected to low-temperature (150 °C) anneal. The observation of narrow, strong components indicates that the erbium
ions form a highly ordered local surrounding (Er-O-Si nanoclusters) in the labile, disordered structural network of a-Si:H.
