excitonic meaning in English
激子的
Examples
- Due to the large exciton binding energy of 60mev , which ensures the high efficient excitonic emission at room temperature , it is regarded as one of the most promising materials for fabricating efficient ultraviolet ( uv ) and blue light emitting devices
由于氧化锌具有较高的激子束缚能( 60mev ) ，保证了其在室温下较强的激子发光，因而被认为是制作紫外半导体激光器的合适材料。 - This direct band - gap material has a large exciton binding energy ( 60mev ) , which permits excitonic recombination even at room temperature . thus zno is attracting much attention as promising candidates for optoelectric applications in visible and ultraviolet regions
它有较高的激子束缚能（常温下为60mev ） ，使得其在室温下可以发射紫外激光，因此作为新一代的半导体发光材料受到广泛关注。 - The wavelength of pump light in white light mode is 400nm . 2 . the excitonic tunneling from cdznse qw to cdse quantum dots under resonant excitation was investigated using femtosecond pump - probe technology on the cdznse quantum well / cdse quantum dots structure
用飞秒脉冲泵浦-探测方法研究了cdse量子点znse cdznse量子阱结构在对cdznse量子阱的激子共振激发条件下激子在量子阱与量子点之间的隧穿。 - 4 . photolumescence and micro - photoluminscence of cdznse qw / znse / cdse qds with different znse barrier thickness was studied to investigate the influence of tunneling on excitonic combination in quantum well and quantum dots . we studied the temperature dependent of the excitonic recombination
通过cdse量子点znse cdznse量子阱结构在不同垒层厚度情况下的发射谱和变温激子发射谱，研究了激子隧穿过程对量子点和量子阱中激子复合的影响。 - Compared to gan , which is one of the most successful wide - band semiconductor materials at present , zno is promising : high - quality zno with very low defect densities can be synthesized at much lower temperature than gan ; zno can emits light with shorter wavelength than blue light emission from gan ; zno has higher excitonic binding energy ( ~ 60mev for zno , 25mev for gan ) , which promises strong photoluminescence from bound excitonic emissions at room temperature ; meanwhile , homogeneous bulk zno is available
和gan相比， zno薄膜具有生长温度低，激子复合能高( zno ： 60mev ， gan ： 21 25mev ) ，受激辐射阈值较低，能量转换效率很高等优点。有可能实现室温下较强的紫外受激发射，制备出性能较好的探测器、发光二极管和激光二极管等光电子器件。
