光子选通多重光谱烧孔中的光致填孔机制
Mechanism of Laser Induced Hole Filling in Photon Gated Multiple Spectral Hole Burning
摘要
报道了给体-受体电子转移型材料zinc-tetraphenylbenzoporphrin+zinc-tetrapheyl benzotribenzoporphrin\phydroxybenzaldhyde\poly (methyl) methacrylate 的光子选通多重烧孔过程。 结果表明要获得高质量的多重光谱孔,从短波往长波的逐次烧孔更为有效。其影响来自与波长有关的光致填孔现象。造成该填孔的主要机制是赝声子边带的作用。理论拟合与实验结果相符。
Abstract
Photon gated multiple spectral hole burning processes have been studied in a donor acceptor electron transfer system. The electron donors of this system are zinc tetraphenylbenzoporphrin and zinc tetraphenylbenzotribenzoporphrin, the acceptor is phydroxybenzaldhyde, and they are doped in the matrix poly(methyl)methacrylate. It is more effective to form high quality multiple holes by successively burning from the shorter wavelength side to the longer side. It is affected by the wavelength dependent phenomenon of laser induced hole filling. The main mechanism of this phenomenon is the exist of pseudo-phonon side band. The theoretical simulation shows fairly good agreement with the experimental results.
