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.
