| 共摻雜樣品和單摻雜樣品的激發(fā)譜和熒光壽命譜圖對比討論顯示,Tb3+離子5D4能級上的電子,除了輻射躍遷發(fā)出487nm的藍光和541nm的綠光之外,還可以借助聲子輔助的作用遷移到達Eu3+的5D1能級,增強了Eu3+在589nm和611nm的光發(fā)射。利用能級圖討論了樣品的白光發(fā)射過程。 |

| Discussions of excitation spectra and fluorescence lifetime spectra of the Co-doped samples and single-doped samples by comparison show that the electronic Tb3 + ions on the 5D4 level can make use of the phonon supporting role migration reaches 5D1 level of Eu3 +in addition to the radiation emitted transition of 541nm blue and 487nm green light .Thus enhanced Eu3 + light emission at 589nm and 611nm . White light emission process of the sample was discussed by energy-level diagram . |
