就本章而言,一个光子是一个具有位置(position),传播方向(direction of propagation)以及波长 λ(wavelength)的光量子。奇怪的是,光子波长使用的国际单位是 纳米(nm),这主要是由于历史原因。其中 1nm=10−9m 。有时会使用另一个单位,埃,其中 埃1nm=10埃 。光子也有一个速度 c ,该速度取决于传播介质的折射...
US20020016250 * Aug 14, 2001 Feb 7, 2002 Makoto Hayakawa Upon irradiation by a light having a wavelength of an energy higher than the bandgap energy of the photocatalyst, water is chemisorbed onto the surface in the form of hydroxyl groups...
We are working at CIOMP on QD lasers for automotive applications like LIDAR or sensing in a wavelength window predicted to show largest eye safety and largest range in foggy air. This window is not accessible to classical double heterostructure lasers based on GaAs or InP. 《Light》记者:高增益...
Upon irradiation by a light having a wavelength of an energy higher than the bandgap energy of the photocatalyst, water is chemisorbed onto the surface in the form of hydroxyl groups (OH − ) whereby the surface of the photocatalytic coating is rendered highly hydrophilic. In certain ...
Nuclear energy is released at the sun’s center as high energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength.比较结构的理解。本题要求听者分辨清所比较之物及其对比关系。原文谈到Nuclear energy(核能)时,将其解释为high energy gam...

The light energy emitted is specific in wavelengths for each element, e.g. sodium emits light of wavelength 589 nm and potassium emits light of wavelengths 404 and 767 nm. The light emitted is proportional to the number of excited atoms present. View chapterExplore book Application of porous ...
g The terminal falling velocity and opening angle of artificial microflier with different payload under light irradiation (Philips infrared lamp, wavelength range: 420–1000 nm, 50 mW cm−2) during the falling process. Full size image Moreover, the terminal falling velocity of as-...
It is already known that there are many factors responsible for the successful formation of a graft union. However, the role of light has been little studied. In an anatomical study, Scanning Electronic Microscope (SEM) was used to explore the effects of
Imaging of resonance Raman spectrometry allowing non-destructive molecular motif identification and quantification was performed to detect structural elements of carotene molecules directly on living aphids. A 488 nm laser wavelength corresponding to the maximum wavelength of carotene absorption was used to...
