关于低压灯丝辅助化学气相沉积金刚石形成过程的研究，在含有H(2)或H(2)和CH(4)的混合环境中，用双光子激光诱导荧光法测定了加热灯丝附近的原子氢的绝对浓度。得到了不同压力、不同灯丝温度、不同直径和不同材料下的径向氢气浓度分布。考察了不同甲烷加入量对H原子浓度的影响。
With respect to the investigation of low pressure filament-assisted chemical vapor deposition processes for diamond formation, absolute concentrations of atomic hydrogen were determined by two-photon laserinduced fluorescence in the vicinity of a heated filament in an environment containing H(2) or mixtures of H(2)and CH(4). Radial H concentration profiles were obtained for different pressures and filament temperatures, diameters, and materials. The influence of the addition of various amounts of methane on the H atom concentrations was examined.
