| 中文摘要 | photoluminescence from gas-evaporated ge nanoclusters consisting of a crystalline core encased in an oxide shell are presented. an as-grown sample shows room temperature luminescence with separate peaks around 357 and 580 nm. prolonged air exposure of the clusters reduces the ge core dimensions, and the emission initially at 580 nm shifts to 420 nm; however, the violet luminescence at 357 nm displays no difference. these results indicate that there are two mechanisms involved with light emission from ge nanoclusters, visible light emission associated with the quantum confinement effect, and violet light emission correlated to luminescent centers.
