【求助】吸收和發(fā)射光譜 已有9人參與
|
| 計算OLED材料,算出來的吸收波長一定比發(fā)射波長要長嗎?為什么呢? |

absorption should have more photon energy than that of emission photon energy. then the system emit extra energy in the form of light. otherwise the material cannot give off light. Photon energy of emission is less, which is called Stroke shift with longer wavelength. Also its named as red shift. In the case of the other way around, emission possessing higher photon energy, its defined as anti-Stroke shift/blue shift. [ Last edited by seainthesky on 2010-7-22 at 23:31 ] |
