【摘要】 将激光染料分子有效地嵌入多孔硅中，获得多孔硅／染料分子复合体。嵌入微量染料分子时，复合体的发光兼有多孔硅和激光染料两者的发光特征，增加染料分子的嵌入量，复合体的发光增强，荧光的时间响应快，脉宽窄，主要表现为激光染料的发光特性。复合体的发光峰位比染料的乙醇溶液有明显兰移更多还原

【Abstract】 Porous silicon/laser dye composite was obtained by efficiently inserting laser dye into porous silicon. The composite shows luminescent property of both the porous silicon and the laser dye when inserting trace dye. Increasing the insert of dye molecules, luminescence of the composite increases, the rise time becomes faster, the pulse width of the luminescence narrows, and the composite shows mainly the luminescent property of laser dye. The luminescence peak position of the composite shifts clearly to the blue compared to that of the same dye in alcohol solution.更多还原
