Electron beam nanoprocessing of a carbon nanotube film using a variable pressure scanning electron microscope.

We demonstrate a novel method of processing carbon nanotubes using a variable pressure scanning electron microscope. Lines were processed in a nanotube film by electron beam irradiation in oxygen gas and nitrogen gas. The processing mechanism can be explained in terms of gas ion sputtering and chemical reaction.

Cathodoluminescence investigation of organic materials.

Cathodoluminescence (CL) properties of various kinds of organic material were investigated for the purpose of staining biological specimens and obtaining CL images. Several kinds of organic light emitting device (OLED) material exhibited CL. The europium complex, Eu(dbm)3(phen), showed the strongest CL signal and was chemically modified for biological staining.
