Abstract

The photoluminescence enhancement of a composite structure on porous silicon with surface-grown silver dendrites was discovered in this study. Silver dendrites are plasmonic antennas that exhibit a slight amplification effect. The small improvement of penetrating light intensity resulted in a significant increase in two-photon absorption, culminating in a remarkable increase in the photoluminescence intensity of the porous silicon material. The manifold enhancement of two-photon absorption was demonstrated by theoretical calculations of its probability.

用多光子显微镜记录银树枝状体对多孔硅光致发光的增强作用

本研究发现了多孔硅上的复合结构与表面生长的银树枝的光致发光增强效应。银树枝状突起是一种等离子体天线，具有轻微的放大效应。穿透光强度的微小提高导致双光子吸收的显著增加，最终使多孔硅材料的光致发光强度显著提高。通过对双光子吸收概率的理论计算，证明了双光子吸收的成倍增强。
