Photovoltaic properties of polymer/Fe2O3/polymer heterostructured microspheres
Article Abstract:
The photovoltaic characteristics of Fe2O3 particles with diameters of 3-5 nm were observed by using transmission electron microscope images. Surface photovoltage spectroscopy was used to study the photovoltaic reactions of the polymer composites, which materialized only when there was an external electric field and if its decay was slower than the Fe2O3 particles. This condition was explained by a reasonable energy band model and it was also suggested that a polymer shell became an electric-passivation layer of the semiconductor Fe2O3 particles.

Spatially confined high-temperature blackbody radiation from C60 films
Article Abstract:
The blackbody radiation from C60/Si layered films were studied using green laser irradiation. Intense white light were emitted as a result and the emission spectra from the visible to the mid-infrared areas agrees with Planck's equation for blackbody radiation. The radiation had effective temperatures of 1100-2140 K, and it was shown that these high temperatures were located in the dark islands formed by laser irradiation of the premodified parts in the composite films.

Spectroscopic investigation of onset and enhancement of electrical conductivity in PVC/PANI composites and blends by gamma-ray or UV irradiation
Article Abstract:
Spectroscopic methods were used to investigate the electrical conductivity of polyvinyl chloride (PVC) with nonconducting polyaniline (PANI) composites and blends when irradiated by gamma-ray or ultraviolet ray. Results showed that the radiation-induced conductivity can be reversed by further exposing the composite films to NH3 vapors. Moreover, the onset of the photoinduced conductivity in both PVC and PVC/PANI films is 300 nm.
