The invention discloses an organic white light device and a preparation method thereof. The organic white light device is composed of an anode, a modification layer, a light-emitting layer, an electron transmission layer and a cathode in turn. The organic white light device is characterized in ...
Chromaticity coordinates of the emitted white light can be tuned by modifying the excitation power density. The effect of Tm and Ho on the luminescence dynamics has been described by analyzing the upconverted emission intensity dependence on the excitation power, as well as from Stokes and decay ...
Answer to: ___ matter is composed of the cell bodies of neurons and makes up the outer cortex of the brain. (a) white (b) green (c) gray...
We report the first observation of white-light emission from femtosecond laser-induced plasma in a water droplet. Such emission is not observed with water in a cell. The microdroplet acts as a lens, focusing the incident light to nanosized regions within itself and directing the emission from ...
Most so-called whites are very light grays: fresh snow, for example, reflects about 80 percent of the incident light, but to be strictly white, snow would have to reflect 100 percent of the incident light. It is the ultimate limit of a series of shades of any color.Compareblack(def19)...
Butterfly wings could be used to inspire new technology in solar cells, according to researchers at the Australian National University (ANU) who said that "filtering" light could be a major feature of future solar projects. IOC Evaluation Commission impressed by Paris passion The International Olymp...
The model predicts that, with a reflector between the diode and the phosphor layer that is blue-light transparent but reflects other visible light, the normalized white light intensity is above 0.9, higher than that of conventional packages (0.6–0.8). 展开 ...
3, without strong oxidant with the use can also play a clarifying effect, can effectively reduce the amount of nitrate and "selenium - cobalt.Application:Use range of compound clarifying agent: bottle glass, glass ball (no alkali, medium alkali), electric light source glass, medicina...
We demonstrate an efficient spectrally broadband and highly directional warm-white-light emitter based on a nonlinear process driven by a cheap, low-power continuous-wave infrared laser diode. The nonlinear medium is a specially designed amorphous material composed of symmetry-free, diamondoid-like ...
If the direction of travel of each ray of light is exactly same, then that light is called collimated light while if the frequency of each ray of light is the same then it is called monochromatic light. Answer and Explanation:1 White light is made up of sev...
