我们研究了含有稳定的氮、氧、氢和氘原子的分子氮纳米团簇的发光。在破坏这些纳米团簇的过程中观察到光谱，伴随着样品中储存的化学能的快速释放。观察到一些有趣的特征，包括在λ = 360 nm附近的宽带，其被鉴定为对应于N4（D2h）聚合氮的2Ag→ 1Ag跃迁的发射。此外，还观察到了λ = 336和473 nm的尖锐谱线，并讨论了它们与ND自由基的关系。
We studied the luminescence of molecular nitrogen nanoclusters containing stabilized nitrogen, oxygen, hydrogen, and deuterium atoms. Optical spectra were observed during the destruction of these ensembles of nanoclusters accompanied by a rapid release of chemical energy stored in the samples. Several interesting features were observed including a broad band near λ ≈ 360 nm, which was identified as emission corresponding to 2Ag→1Agtransition of N4(D2h) polymeric nitrogen. Also the sharp lines at λ ∼ 336 and 473 nm were observed, and their assignments to ND radicals are discussed.
