受激发射

Zinc oxide is an n-type direct band-gap semiconductor material. Due to the large exciton binding energy of 60 meV, which ensures the large exciton emission at room temperature, it is regarded as one of the most promising materials for fabricating efficient ultraviolet blue light emitting device.

氧化锌是直接带隙宽禁带半导体材料，具有较高的激子束缚能(~60meV)，可以实现室温下的紫外受激辐射，在紫外发射器件等领域具有广阔的应用前景。

A spectral line is emitted when an atom proceeds from an excited state to a lower state.

当原子从一个受激态进入另一个较低的状态时，就发射一条谱线。

The spectral performance of a self-Raman-active material (Nd:SrMoO4 crystal) was investigated. Its stimulated Raman scattering, absorption spectra, luminescence lifetime, and infrared emission under 808 nm LD excitation were measured at room temperature.

通过拉曼散射光谱，吸收光谱，荧光发射寿命和808 nm LD激发下的红外荧光光谱的实验测量，系统研究了Nd3+：SrMoO4晶体的自受激拉曼光谱性质。

This production of light with the same characteristics as the original light, called stimulated emission, is responsible for the many extraordinary properties of laser radiation.

这个生产轻具有相同的特点，作为原来的轻，所谓的受激发射，是负责为许多不平凡的性能的激光辐射。

The study of fluorescence spectrum proved that the excited phenylenerings of amorphous PES copolymer with high density phenylenerings in its main chain could form an excimer with the surrounding unexcited phenylenerings, and the emission peak intensity of excimer was strengthened with the increase of aging time.

荧光光谱的研究证明，非晶态聚醚砜共聚物由于主链苯环密度较高，苯环受激处于激发态时易与周围激态苯环相互作用形成激基缔合物，缔合物发射峰的强度随老化时间增加而增强。

The femtosecond irradiation spectra was used to measure the radiation kinetics process. Fitted by the two exponent model, two time peaks were obtained, corresponding to the interband radiation and the surface defect radiation respectively. This results also strongly suggests that there are two relaxation pathways in the nanocomposite.

利用飞秒发射光谱观测凝胶玻璃中ZnSe纳米粒子发光动力学过程，采用双指数模型进行拟合，得到了两个时间组分：11.2ps和550ps，分别对应纳米品的带间发光和表面缺陷态发光，进一步证实了半导体纳米晶材料受激辐射的两种发光途径的存在。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
