| 摘 要： | 通过毛细生长法沉积了具有特定光子禁带的胶体光子晶体, 并用浸渍法在光子晶体孔隙内浸润了Rhodamine 6G(R6G)乙醇溶液, 制备了掺杂R6G的光子晶体. 结果发现, 光子晶体的禁带对R6G的发光谱有影响, 能够强烈限制光子的发射从而抑制特定波长的发光强度. 改变掺杂R6G的浓度, 会引起间隙介质平均折射率的变化, 从而引起光子带隙的移动. 采用Nd:YAG激光器三倍频354.5 nm激光对掺杂了R6G的光子晶体进行了激发, 光谱显示没有受激发射, 这一点与相关文献是一致的. 我们对光子晶体中R6G的聚集态进行了SEM分析, 发现R6G呈束状聚集. 与胶体光子晶体的111]方向相比, 该束状聚集体更倾向于沿着100]方向生长. 本实验对于开展固态激光器的研究以及三维阵列的应用研究具有一定指导意义.

| Abstract: | A colloidal photonic crystal(CPX) was prepared by capillary force deposition for an intended photonic band gap.Laser dye rhodamine 6G(R6G) was embedded into the prepared CPX by a dipping method.Experimental results demonstrate that the photonic band gap influences the emission spectra of R6G.Increasing the content of R6G leads to an increase in both the lumi-nescence intensity and the average refractive index of the interspace,and the latter will cause a systematic red shift of the photonic band gap.The emi... |
