Electrons change energy states by either resonantly gaining energy from absorption of a photon or losing energy by emitting photons. In chemistry-related disciplines, one often distinguishes between fluorescence and phosphorescence. The former is typically a fast process, yet some amount of the original energy is dissipated so that re-emitted ...
Star Wars: Clone Wars or The Clone Wars are titles of various series of comics set in the Star Wars universe during the Clone Wars conflict. Dark Horse Comics published a nine-volume series of trade paperbacks (2003–2006) collecting various comics dealing with the conflict, a ten-volume graphic-novella series titled Clone Wars: Adventures (2004–2007) in the style of the 2D animated series ...
Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs.
A corollary of Kasha's rule is the Vavilov rule, which states that the quantum yield of luminescence is generally independent of the excitation wavelength. [4] [7] This can be understood as a consequence of the tendency – implied by Kasha's rule – for molecules in upper states to relax to the lowest excited state non-radiatively.
Phosphorescent materials continue to emit light for some time after the radiation stops. This difference in timing is a result of quantum spin effects. Fluorescence occurs when a photon of the incoming radiation is absorbed by a molecule exciting it to a higher energy level followed by emission of light as the molecule returns to a lower energy ...
Star Wars is an American epic space-opera media franchise, centered on a film series created by George Lucas.This is a list of the many reference books that have been published to accompany the films, television series, and the Expanded Universe of books, comics and video games.
This is a list of Star Wars comic books set in the fictional Star Wars universe. Star Wars comic books were originally published by Marvel Comics, starting with the original series in 1977 and ending in 1984. [1] Blackthorne Publishing published a run of 3-D comics from 1987 to 1988, [2] and Dark Horse Comics published Star Wars comic books ...
A simplified Jablonski diagram illustrating the change of energy levels.. The principle behind fluorescence is that the fluorescent moiety contains electrons which can absorb a photon and briefly enter an excited state before either dispersing the energy non-radiatively or emitting it as a photon, but with a lower energy, i.e., at a longer wavelength (wavelength and energy are inversely ...
