In this work we have explored the photoluminescence signal emitted by graphene oxide (GO) nanosheets infiltrated in silanized porous silicon (PSi) matrix. A strong enhancement of the PL emitted from GO by a factor of 2.5 with respect to GO on crystalline silicon was successfully demonstrated. In addition, a weak wavelength modulation of GO photoluminescence emission was observed, resulting in very attractive aspect for its exploitation in innovative optoelectronic devices and high sensible fluorescent sensors.

Abstract
In this work we have explored the photoluminescence signal emitted by graphene oxide (GO) nanosheets infiltrated in silanized porous silicon (PSi) matrix. A strong enhancement of the PL emitted from GO by a factor of 2.5 with respect to GO on crystalline silicon was successfully demonstrated. In addition, a weak wavelength modulation of GO photoluminescence emission was observed, resulting in very attractive aspect for its exploitation in innovative optoelectronic devices and high sensible fluorescent sensors.File in questo prodotto:
