典型含氮化合物在氮气中的等离子体特性
Plasma Characteristics of Typical Nitrogen-containing Compounds in Nitrogen Atmosphere
摘要
Abstract
Nitrogen-containing compounds,acting as nitrogen donors,directly influence the types of high nitrogen compounds formed under laser irradiation.To understand the impact of various nitrogen-containing compounds on the formation of high-nitrogen compounds,three representative compounds NaN3,Si3N4 and P3N5 were ablated using a pulsed Nd:YAG laser in a nitrogen atmosphere.The plasma characteristics and the evolution of the transient intermediates generated by laser sputtering were investigated by transient spectrometer.The findings indicate that the laser ablation of NaN3 yields the highest number of ni-trogen atoms(NⅠ),monovalent nitrogen ions(NⅡ),and trivalent nitrogen ions(NⅢ),with the longest duration of nitrogen plasma.The lifetimes of NⅠ,NⅡ,and NⅢ reached 39,400 ns,39,400 ns,and 19,450 ns,respectively.Among the three ni-trogen donors,the laser ablation of NaN3 in a nitrogen atmosphere is most likely to result in the formation of high-nitrogen or all-nitrogen compounds.关键词
