The fluorescence of grapliene oxide quantum dots(GOQDs) that are infiltrated into porous silicon(PSi) is investigated. By dropping activated GOQDs solution onto silanized PSi samples. GOQDs are successfully in?filtrated into a PSi device. The results indicate that the intensity of the fluorescence of the GOQD-infiltrated multilayer with a high reflection band located at its fluorescence spectra scope is approximately double that of the single layer sample. This indicates that the multilayer GOQD-infiltrated PSi substrate is a suitable material for the preparation of sensitive photoluminescence biosensors.
