Photoluminescence enhancement of graphene oxide emission by infiltration in an aperiodic porous silicon multilayer.
Graphene oxide (GO) is a photoluminescent material whose application in integrated optoelectronics has been strongly limited due to poor emission intensity and handling procedures not compatible with standard microelectronic ones. In this work, a hybrid GO-porous silicon (GO-PSi) structure is realized in order to investigate the emission properties of GO infiltrated into an aperiodic porous multilayered matrix. A photoluminescence enhancement by a factor 32, compared to the same amount of GO deposited on a flat silicon surface, is demonstrated. Photoluminescence measurements also show wavelength modulation of the emitted signal.
