But the vast majority of the matter in the universe may not emit photons of any wavelength.
但是宇宙中大多数的物质也许不会发射任何光子(无论其波长为何)。
These two photons in turn could stimulate two other atoms to emit photons, yielding four photons.
这两个光子接著会激发另两个原子放出光子而产生四个光子。
Living systems may emit photons in response to stress and generate an ultra-weak luminescence bio-image.
生物体可以应激而发射光子生成超微弱发光图像。
They also embedded quantum dots, tiny semiconductors that can emit a single photon at a time, in the waveguide as a proxy for atoms that could become entangled with the photons.
他们还在波导中嵌入了量子点(一种能释放单光子的微小半导体)作为代理来使原子与光子产生纠缠。
They subsequently "de-excite" and emit mid-infrared light particles, or photons.
随后进入衰退期，释放出中等大小的红外光子或是光子。
The holes and electrons, combine to form photons, thereby causing the electroluminescent semiconductor layer to emit visible light.
空穴和电子结合而形成光子，从而使得电致发光半导体层发出可见光。
