有机光子选通烧孔材料中受体浓度对光致填孔的影响研究

EFFECT OF ACCEPTOR CONCENTRATION ON LASER INDUCED HOLE FILLING IN ORGANIC PHOTON-GATED SPECTRAL HOLE-BURNING MARTERIALS

研究了光谱烧孔的填孔过程，在几种有机电子转移型永久性烧孔材料中，得到了光谱烧孔的光擦除过程中孔的擦除程度随样品中受体浓度的减少而减弱，并受擦孔光的光子能量影响，同时与受体本身性质有关的实验结果．得出填孔过程也是一种电子转移过程的结论，并提出了一个能级模型对实验结果进行了分析．

his paper reports laser induced hole filling (LIHF) in organic photon gated spectral hole-burning materials. A law was obtained that extent of LIHF decreases with the decrease of acceptor concentration, and it related to the photon-energy of laser for hole filling and the nature of acceptor. The processes of hole filling is a electron tranfer process via tunneling on excited states.
