摘要

为了优化液晶类微管激光器的性能，拓展其应用领域，本文研究了银纳米颗粒和氧化锌纳米颗粒对染料掺杂聚合物稳定液晶微管激光器出射激光的影响。通过掺杂不同浓度的银纳米颗粒和氧化锌纳米颗粒在聚合物稳定液晶的微管随机激光器中，探究其对微管激光器出射激光特征的影响，并对比两种纳米颗粒的影响效果。实验结果表明：当在聚合物稳定液晶微管激光器中掺入0.1%的银纳米颗粒后，随机激光出射强度增强，其激光阈值从23.2

J/pulse减小至10.9

J/pulse。当氧化锌纳米颗粒的掺杂浓度达到1.0%时，在随机激光出射强度增加的同时，激光出射阈值会减小至21.2

J/pulse。然而，过量纳米颗粒的掺杂均会造成随机激光出射光强的降低和激光阈值的增加，其原因在于纳米颗粒团簇的产生，降低了纳米颗粒的散射作用。实验结果还表明，银纳米颗粒掺杂对微管激光器性能的提升明显优于氧化锌，这归因于银纳米颗粒所引发的局域表面等离共振效应会增强其散射作用。通过掺杂纳米颗粒，微管随机激光器的性能得到了提升，为其在通讯、加密以及液晶显示等领域奠定了基础。

Abstract

This paper investigated the improvement of random lasing properties based on dye-doped polymer stabilized liquid crystals (DDPSLC) by doping Ag and ZnO nanoparticles (NPs) with different concentrations in capillaries

in order to expand new applications for this device. At first

DDPSLC samples with different dye doping concentrations were prepared in capillary tubes to select an optimum DDPSLC system for doping NPs. After selecting the optimum DDPSLC

some Ag NPs and ZnO NPs with different concentrations were added into the DDPSLC to investigate the effect on the random lasing properties. The experimental results indicate that the random lasing threshold decreased from 23.2

J/pulse to 10.9

J/pulse after doping 0.1% Ag NPs into DDPSLC. As the doping concentration of ZnO NPs increased to 1%

the lasing properties can be also improved due to the scattering effect of ZnO NPs

and the lasing threshold of the DDPSLC decreased slightly to 21.2

J/pulse. As the doping concentrations of NPs continually increased

some NPs clusters can be observed obviously in capillary samples

which have a negative effect on random lasing emission. In addition

doping Ag NPs with optimum concentrations (0.1%) can enhance the random lasing properties more significantly because of the improvement of scattering effect caused by localized surface plasmon resonance (LSPR). The random lasing devices based on DDPSLC containing Ag NPs or ZnO NPs will have widely potential applications in LC display

communications and encryption technology.
