Abstract: Plasmonic gratings of different periodicities are fabricated on top ofSilicon nanocrystals embedded in Silicon Dioxide. Purcell enhancements of up to2 were observed, which matches the value from simulations. Plasmonicenhancements are observed for the first three orders of the plasmonic modes,with the peak enhancement wavelength varying with the periodicity. Biharmonicgratings are also fabricated to extract the enhanced emission from the firstorder plasmonic mode, resulting in enhancements with quality factors of up to16.
