CN(X2+)自由基的密度被认为是形成非晶氮化碳膜的前体,通过CN(A2 i-X2+)、4-0、5-1和7-2带的激光诱导荧光(LIF)光谱测量。在0.1Torr的气压下,通过微波(MW)放电流激发BrCN产生CN(X2 ~+)自由基,并在引入BrCN的喷嘴尖端下游观察到LIF光谱。通过光谱模拟分析和Ar原子对瑞利散射强度的校准来评估单个跃迁的LIF强度。CN(X2+)密度估计为9.9×1017 m-3。使用先前测定的Ar+密度[H]分析该密度。Ito等人:JPN. J.Appl.Phys.43(2004)7277],提出CN(X2 ~+)的主要产生和损失过程分别是BrCN ~+-e-复合和与BrCN的猝灭.
The density of CN(X2Σ+) radicals, which are considered to be the precursor to the formation of amorphous carbon nitride films, was measured by laser-induced fluorescence (LIF) spectroscopy of the CN(A2Πi–X2Σ+), 4-0, 5-1, and 7-2 bands. The CN(X2Σ+) radicals were produced by the dissociative excitation reaction of BrCN with microwave (MW) discharge flow of Ar under the pressure of 0.1 Torr, and the LIF spectra were observed just downstream of the nozzle tip from which BrCN was introduced. The LIF intensity for the individual transition was evaluated by spectral simulation analysis and by calibration against the Rayleigh scattering intensity by Ar atoms. The CN(X2Σ+) density was evaluated to be 9.9×1017 m-3. This density was analyzed using the previously determined Ar+ density [H. Ito et al.: Jpn. J. Appl. Phys. 43 (2004) 7277], and it is suggested that the dominant production and loss processes of CN(X2Σ+) are BrCN+-e- recombination and quenching with BrCN, respectively.
