Abstract

Scattering of light by disordered structures is normally detrimental to their applicability in many optoelectronic devices. However, some micro and nanostructures are useful in enhancing several optical and thermal properties like emission, heat diffusion etc. For this purpose, we have optimized the low temperature hydrothermal growth method for the ZnO micro tubes which leads to the growth of ZnO as mono dispersed micro tubes. Further, these samples were used to enhance the fluorescence efficiency of disordered media consisting of micro tubes of ZnO and fluorescein dye and to optimize the thermal diffusion of the mixture which will help us optimize the composition of these microscopic inclusions in designing a random lasing medium. Dual beam thermal lens method was used for this purpose.

含ZnO微管和荧光素染料的多相微流体的热扩散特性和光致发光的实验研究

摘要

无序结构对光的散射通常不利于其在许多光电设备中的适用性。但是，某些微结构和纳米结构可用于增强一些光学和热学性质，例如发射，热扩散等。为此，我们优化了ZnO微管的低温水热生长方法，从而导致ZnO以单分散的形式生长微管。此外，这些样品用于增强由ZnO和荧光素染料微管组成的无序介质的荧光效率，并优化混合物的热扩散，这将有助于我们在设计随机激光介质时优化这些微观夹杂物的组成。为此使用了双光束热透镜法。
