摘　　要：利用“四能级”模型,对吸附于金属岛膜上的染料分子的表现荧光增强因子随分子表面覆盖度和分子的荧光量子效率的变化进行了理论分析,同时测量了吸附于银岛膜上的荧光素钠分子和若丹明6G分子的表观荧光增强因子随分子荧光量于效率的变化。Theoretical analyses of the dependence of apparent fluorescence yield YF on molecular fluorescence quantum efficiency QE and molecular coverage have been made by using 'Fourlevel model. The experimental studies of apparent yield Y_Y of SF and Rh6G molecules adsorbed on-chemically deposited silver island film are reported. The experimental results are in agreement with the theoretical expectation.
