摘要

本研究报道了金纳米颗粒(AuNPs)掺杂的向列相液晶(LC)的光致发光(PL)。结果表明，掺入AuNPs后，MBBA LC的发光强度得到提高，且随AuNPs浓度的升高，发光强度的提高幅度增大。此外，由于aunp的存在，排放峰也发生了变化。结果表明，在0.1 AuNPs的作用下，LC的发光峰向更长波方向移动了78nm。少量的aunp可以提高PL强度。本研究报道了金纳米颗粒(AuNPs)掺杂的向列相液晶(LC)的光致发光(PL)。结果表明，掺入AuNPs后，MBBA LC的发光强度得到提高，且随AuNPs浓度的升高，发光强度的提高幅度增大。此外，由于aunp的存在，排放峰也发生了变化。结果表明，在0.1 AuNPs的作用下，LC的发光峰向更长波方向移动了78nm。少量的aunp可以提高PL强度。

Improvement photoluminescence of nematic liquid crystal doped with gold nanoparticles

This study reported the photoluminescence (PL) of nematic liquid crystal (LC) doped with gold nanoparticles (AuNPs). Our results demonstrated PL emission intensity of MBBA LC is improved with doping AuNPs, and the improvement of PL intensity increased with elevating concentration of AuNPs. As well as, the emission peak is changed due to presence of AuNPs. It was showed PL emission peak of LC has been shifted towards longer wavelength by 78nm in presence of 0.1 AuNPs. A small amount of AuNPs can be improved the PL intensity.This study reported the photoluminescence (PL) of nematic liquid crystal (LC) doped with gold nanoparticles (AuNPs).
