BaLaB9O16: Eu, Tb in the vacuum ultraviolet spectral characteristics

Spectrum is 1701Lrll field before the post-broadband and narrowband constitute 170n. Which is located in front of the broadband 1701Lrll the absorption by the substrate caused. 170 ~ 260nm narrow band is a Tb3 + in the 4f 5d transition absorption. Th Excited at 147nm, the emission spectra are shown in Figure 4 shows the emission spectrum is located near the fields 485,540,[link widoczny dla zalogowanych],588 and 623n 4 lines form, they belong to D4 of a F (J = 6, closed lotus Date: 2001 a G9-21; revision date :2001-11-10 Foundation item: National Natural Science Foundation of China (20071031) About the author: You Hong Qing (1965 a), male, Linyi,[link widoczny dla zalogowanych], Shandong people, Bo soil, Research Associate ; research: efficient light-emitting materials, Rare Earth l9 6lO volume, nm Figure 6 1BaI ugly o8Eu02B9O】 excitation spectra of t] nln excitation spectra of Figure 3I2B9Ol6 5,4,3) transition. 3 Conclusion The high temperature solid state reaction of the BaLaB90l6: RE (1iE = Eu,[link widoczny dla zalogowanych], Tb) plasma phosphors, studied their vacuum violet excitation and corresponding emission spectra and found that boron oxygen anionic groups host absorption band at 150 a nearby , Eu3 displacement of the charge transfer band near 250nm, Tb of the 4f-5d absorption at 150 ~ 260nm in the region,[link widoczny dla zalogowanych], and observed that the Q matrix with the existence of rare earth ion energy transfer. } / Nl Wu Figure 2BaI emission spectrum of the ugly osEu02B9016
