摘要:
将铬/氮化硼(Cr/BN)混合粉末经压片机制成直径为13 mm、厚度为2~5 mm的底物,然后在反射式飞行时间质谱仪上,以高纯氮气为载气,用激光轰击Cr/BN底物,生成了铬杂氮团簇CrNn+n=2、4、6、8),得到其质谱图。用波长为266 nm的激光对CrN6+和CrN8+进行了光解,获得其光解质谱图,探讨了铬杂氮团簇的组成。结果表明,生成的铬杂氮团簇中最稳定的团簇为CrN8+,这些团簇的组成依次相差2个氮原子,推测生成的铬杂氮团簇CrN8+由Cr+和N2构成。
Abstract:
The substrate with a diameter of 13mm and thickness of 2-5 mm was prepared by compressing Cr/boron nitride (BN) mixed powder using a pressing tablet mechine, and then on a reflection type flight time mass spectrometer, using high purity N2 as carrier gas, the Cr/BN substrate was ablated with the laser, the Cr-doped nitrogen clusters CrNn+ (n=2,4,6,8) were generated and its mass spectrogram was obtained. The photodissociation of CrN6+ and CrN8+ was performed by laser with a wavelength of 266 nm, its photodissociation spectrogram was obtained, and the compositions of Cr-doped nitrogen clusters were discussed. The results show that in generated Cr-doped nitrogen clusters CrNn+,CrN8+ is more stable, which are composed in a difference of two nitrogen atoms in turn, predicting that CrN8+ is composed of Cr+ and N2.
