| 英文摘要 | Correlations between si nanocrystal (nc-si) related photoluminescence (pl), er3+ emission and nonradiative defects in the er-doped sio2 films containing nc-si (srso) are studied. upon 514.5 nm laser excitation the erbium-doped srso samples exhibit pl peaks at around 0.8 and 1.54 mum, which can be assigned to the electron-hole recombination in nc-si and the intra-4f transition in er3+, respectively. with increasing er3+ content in the films, er3+ emission becomes intense while the pl at 0.8 mum decreases, suggesting a strong coupling of nc-si and er 31 ions. hydrogen plasma treatment for the samples improve the pl intensities of the 0.8 and 1.54 mum bands, indicating h passivation for the nonradiative defects existing in the samples. further-more, from the effect of hydrogen treatment for the samples, we observe variation of the number of nonradiative defects with annealing temperatures.
