Novel graphitizable pitches with controllable softening points and methylene-bridged structures were successfully prepared through photobromination of 1-methylnaphthalene (1-MNa) followed by closed-system dehydrobromination (CSD). The structures of b

Novel high-carbon-yield pitches were prepared through the iodination of 1-methylnaphthalene (1-MNP) followed by dehydroiodination/polycondensation. 1-MNP was first iodinated by I2 with the aid of I2O5, yielding mainly 1-iodo-4-MNP. Then, a thermal-de

The photoluminescence of Mn2+ in ZnS:Mn2+ nanoparticles with an average size of 4.5 nm has been measured under hydrostatic pressure from 0 to 6 GPa. The emission position is red-shifted at a rate of -33.3+/-0.6meV/GPa, which is in good agreement with

The photoluminescence of porous silicon can be modified sensitively by surface adsorption of different kinds of molecules. A quite different effects of 9-cyanoanthracene and anthracene adsorption on the photoluminescence of porous silicon were observ

The GaSb and Ga0.62In0.38Sb nanocrystals were embedded in the SiO2 films by radio-frequency magnetron co-sputtering and were grown on GaSb and Si substrates at different temperatures. We present results on the 10K excitonic photoluminescence (PL) pro

The luminescent nanocrystal Ge embedded in a-SiO2 matrix was prepared by thermal oxidation of a-Si1-xGex:H films under conventional conditions. It was found that nc-Ge were formed through the selective oxidation of Si in a-GexSi1-x:H alloys and preci

It is weL.L. known from the phonon dispersion curves of bulk GaAs and AlAs that though their acoustic branches basically overlap, the optical branches do not. As a consequence, in GaAs/AlAs superlattices the acoustic phonon modes are the folded modes
