摘要

本文介绍了纳米晶多孔硅的光致发光特性。在相当新鲜的样品中观察到两个最大值,一个位于可见范围的红外边缘,另一个位于红色。老化后,第一个最大值消失,这表明它与表面状态有关,而红色最大值经历了显著的蓝色偏移。一个简单的量子约束模型允许将红色最大值的光子能量与两个约束能级之间的跃迁联系起来,并根据氧化引起的尺寸减小来解释蓝移。这些结果与先前的显微结构测量结果一致。

Quantum confinement in the photoluminescence of nanocrystalline porous silicon
The paper presents the photoluminescence of nanocrystalline porous silicon. Two maxima were observed for rather fresh samples, one located at the infrared edge of the visible range and the other one in red. After ageing, the first maximum vanishes, suggesting its relation with the surface states, while the red one undergoes a significant blue shift. A simple quantum confinement model allows to correlate the photon energy of the red maximum with a transition between two confinement levels and to interpret the blue shift in terms of size reduction by oxidation. These results are in good agreement with previous microstructure measurements.
