我们研究了一个量子力学模型，通过一个能够维持电磁共振的小粒子的存在来增强荧光产率和光化学速率。球体通过从分子中获取能量并将其存储在辐射模式中来降低吸收和发射效率，通过增加局部场来增强吸收，并通过有效地将从发射状态转移到粒子的辐射电磁共振的能量发射出来来增强荧光。本文研究了这些效应的相互作用如何影响荧光强度和光化学反应的速率。
We examine a quantum mechanical model for the enhancement of fluorescence yield and photochemical rates by the presence of a small particle capable to sustain electromagnetic resonances. The sphere lowers the absorption and emission efficiency by taking energy from the molecule and storing it intononradiative modes, enhances the absorption by increasing the local field, and enhances the fluorescence by emitting efficiently theenergy transferred from the emitting state to a radiative electromagnetic resonance of the particle. The present paper studies how the interplay of these effectsmodifies fluorescence intensity and the rate of photochemical reactions.
