Surface plasmon resonant emission from Ag dispersed ZnO films fabricated by molecular precursor method

摘要

ZnO films dispersed with Ag nanocrystals (Ag-NC/ZnO) were fabricated by the molecular precursor method. Electrical and optical properties of the films and their application on the GaInN-based blue LEDs were studied through the observations of photoluminescence (PL) spectra and analytical simulations. Although the enhancement of the blue LED emission was not observed, the PL spectra exhibited additional emission peaks in the yellow spectral region. Judging from their spectral shape, they were ascribed to the surface plasmon resonant emission.
