摘要: Abstract Si–O–C nanotubes were produced by pyrolyzing polycarbosilane (PCS) inside cylindrical pores of anodized aluminum oxide (AAO) templates between 900 and 1100 °C. The diameters these 250 350 nm. analyzed SEM, TEM, EDS, FTIR Raman spectroscopy. composed a mixture oxycarbide glass carbon clusters. ratio Si:O:C in the was about 1:0.97:3.3. Electron emission investigated current–voltage characterization at an anode-to-specimen distance 67 μm. electric field for obtaining electron to current density 10−4 A/cm2 from 7 V/μm.
