我们研究了用金薄膜修饰的硅纳米晶的自发辐射衰减率。结果表明，由于连续金膜的沉积，由光发射衰减曲线分析得到的衰减率分布的平均值和标准偏差值增大。这些值取决于金膜厚度和发射波长。观察到的结果很好地解释了使用点偶极子衰减率模型考虑到有效的介电函数的金膜，表现出奇特的结构中的局部表面等离子体共振区域。
We investigate the spontaneous emission decay rate of Si nanocrystals modified by thin semicontinuous gold films. It has been shown that the mean and standard deviation values of decay rate distribution obtained from the photo-emission decay curve analysis increase due to the deposition of semicontinuous gold films. These values are dependent on gold film thickness and emission wavelength. The observed results are well explained using a point-dipole decay rate model considering the effective dielectric functions of the gold films that exhibit peculiar structures in the localized surface plasmon resonance region.
