Luminescence in Porous Silicon – Poly(Para–phenylene) Hybrid Nanostructures

Effect of the polymer coating on the structure and luminescent properties of the hybrid layer nanoporous silicon (PS)-polyparaphenylene (PPP) has been studied. For preparation of PS layer a silicon wafer with n-type of conductivity was used. The PS-PPP structures were characterized by FTIR spectrosc...

Description
Summary:Effect of the polymer coating on the structure and luminescent properties of the hybrid layer nanoporous silicon (PS)-polyparaphenylene (PPP) has been studied. For preparation of PS layer a silicon wafer with n-type of conductivity was used. The PS-PPP structures were characterized by FTIR spectroscopy, scanning electron microscopy and investigated on the ability to photo- and cathodoluminescence at T= 78 and 293K. It has been found that intensity of luminescence in the hybrid structure based on PPP and PS significantly increases as compared with intensity of photo- and cathodoluminescence of PS without polymer. The possible mechanism of such effect is discussed.
