Spontaneous Emission Characteristics of Quantum Dots Near Non-Concentric Nanoshells
摘要
Abstract
To investigate the spontaneous emission characteristics of quantum dots near non-concentric sodium-gold(Na,Au)nanoshells,the local response approximation(LRAM),hard-wall hydrodynamic model(HDM),and quantum hydrodynamic model(QHDM)were employed to analyze the effects of core displacement and size scaling on the spontaneous emission intensity.The results demonstrate that as the core shifts from the bottom to the top of the shell,the spontaneous emission intensity decreases,accompanied by a resonance peak shift that first blueshifts and then redshifts.Additionally,increasing the size of the non-concentric nanoshell leads to a reduc-tion in the quantum dot's spontaneous emission intensity.关键词
