Optical properties of poly(9,9’-di-n-octylfluorenyl-2.7-diyl)/amorphous SiO2 nanocomposite thin films

Identified as potential materials for optoelectronic applications, the polymer/inorganic nanocomposites are actively studied. In this work, the effect of amorphous silica nanoparticles (NPs) content on the optical properties of Poly (9,9’-di-n-octylfluorenyl- 2.7-diyl) (PFO) thin films has been inve...
