Pressure Effect on Electrical Properties and Photoluminescence Spectra of Solid C60 and C70 Fullerenes

Optical and electrical properties amorphous carbon nitride (a-CN) has been investigated on films deposited by reactive R.F. sputtering source with a graphite target. The amorphous carbon nitride samples were prepared under a gas mixture of nitrogen (N2) and /or Argon (Ar).The optical transitions are governed by the  and * electronic state distributions, related to sp2- and sp1-hybridized C and N atoms. Specific lonepair electronic states arise from groups (CN) with sp1-hybridized C atoms, which may form C≡N triple bonds or —N=C=N— longer chains. Photoluminescence spectra show a maximum around 650 nm. Two conduction regimes at high and low temperature are found in a-CN samples. The corresponding activation energies decrease with the increase of target voltage.

AbstractUltra-Fine ZnO nanobelts are grown via thermal evaporation and condensation method without the use of any catalyst on the substrates. These nanobelts have an average width of about 5.8 nm. Photoluminescence spectra reveal that there is a blue shift in the near band edge ultra violet emission from 381 nm to 367 nm equal to 124 meV. These ultra-fine nanobelts have been studied for size induced optical and electrical properties.

AbstractComposites based on polyvinylchloride with incorporated CdSe/ZnS nanoparticles are produced. The optical and electrical properties of the polymer composites containing CdSe/ZnS nanoparticles are studied. The absorption and photoluminescence spectra of the composites are recorded, and their bulk resistivities are measured. The CdSe nanoparticle dimensions are determined. It is established that, upon short-term heat treatment, the photoluminescence intensity increases, whereas upon heating for a long time, the photoluminescence intensity substantially decreases.
