Resumen:

In this work, we active the defect mode of a porous Si-SiO2 microcavity embedded with ZnO photoluminescent nanoparticles by means of a 350nm laser. ZnO nanoparticles were obtained by Sol-gel method and were placed over the porous surface of the microcavity by drop coating method. Optical properties and morphological were determinate employed UV-Vis-IR, SEM and photoluminescence spectroscopic. We found that the position and bandwidth of the photoluminescence spectrum corresponds to the active mode of the microcavity. © 2024 IEEE.
