本文使用表面修饰的光学布洛赫方程和镜象法,对小颗粒金属表面吸附原子的荧光和共振荧光等光学特性进行理论研究.着重讨论吸附原子的自发辐射寿命、跃迁频移、共振荧光谱、偶极矩的压缩以及吸收线宽等,研究小颗粒金属的尺寸效应以及吸附原子与它之间距离的变化对上述光学性质的影响.

Spontaneous emission and resonance fluorescence of an adatom adsorbed near a smail metallic particle are studied by means of the surface-dressed optical Bloch equations and the modified image theory. Spontaneous decay time and Lamb shift; resonance fluorescence spectrum, squeezing effects, and absorption lineqidth are discussed. The influences of size effects, distance between the adatom and particle, and fluctuation in the laser intensity on the optical property are analyzed.
