查询词典 photons

Confronting the run of RHIC, the study about the signals of deconfinement and partial restoration phase transitions under extreme environment is the hot topic in high energy circles. In particular, because the FM signals: dileptons and photons can pene- trate the medium almost undisturbed and are considered to be the clearest ones, have drawn much attention.

If under ideal conditions, one electron-hole pair injected yields one blue photon and the quantum efficiency of the phosphor equals one, the numbers of electron-hole pair must equal to the numbers of white photons. So LW white LED radiation power output has to consume 1.51 W electric powers and the luminous flux efficiency limitation of electrical to optical conversion for the white LED is 197.8lm/W at above condition.

在理想情况下，注入一个电子－孔穴对产生一个蓝光光子，设荧光粉的量子效率为1，因此，注入的电子－孔穴对数亦等于白光光子数，进而计算出白光LED每辐射1W的光功率所需的电功率为1.51W，上述白光LED发光光谱对应的白光LED的电－光转换的理论极限流明效率为197.8lm/W。
