掺杂Bis-MSB紫外激光染料的聚苯乙烯小球单分子层周期阵列形成的可见光衍射

Visible Light Diffraction in a Monolayer Periodic Array of UVLaser Dye Bis-MSB Doped Polystyrene Spheres

光子晶体是近年来全世界的研究热点之一。文中探讨了在实验室中用自组装的方法制备聚苯乙烯小球二维胶体晶体的过程,并实验研究了He-Ne激光器发出的激光束聚焦到样品上所产生的可见光衍射图案。

Photon crystal is a new focus of research in the world. The research aspect of this article originated from USA, yet there is no related report in Chinese literature. In the article we discussed the process of prepairing two-dimensional colloidal crystal of polystyrene spheres using self-assembling method in laboratory. In our experiment, a helium-neon laser beam was focused on the sample and produced visible light diffraction pattern. In the end the beautiful future prospect on photon crystal are briefly discussed.
