VUV and UV spectroscopy of ns2 ions co-doped with Tb3+ ion in Ln(BO2)3 (Ln=La, Gd)

Investigation and application of quantitative relationship between sp energy levels of Bi3+ ion and host lattice

“…Now let us deal more fully with the inconsistent assignment of C band of Bi 3 þ ion in Gd(BO 2 ) 3 that touched on earlier. De Hair assigned the band with a maximum at 5.17 eV as A band and 6.20 eV as C band [16], however, Tanimizu assigned excitation band with peak at 5.10 eV as A band but 6.30 eV as B band, 8.11 eV as C band [17]. Using our obtained Eq.…”

“…Some assignments are only tentative and sometimes even contradict with each other. For example, for Bi 3 þ -doped Gd(BO 2 ) 3 , De Hair assigned the band with a maximum at 240 nm (5.17 eV) as A band and 200 nm (6.20 eV) as C band [16], however, Tanimizu assigned excitation band with peak at 8.11 eV as C band but 6.30 eV as B band [17]. What's more, position of C band of Bi 3 þ ion in some compounds sometimes cannot be very accurate due to instrumental limitations [18], and sometimes cannot be distinguished because it was overlapped by the host-lattice absorption band [19].…”

Excitation light source dependence of emission in Sn2+-Ce3+ codoped ZnO-P2O5 glasses

“…In addition, the transition probability is high enough for practical phosphor, such as Sb 3þ , Mn 2þdoped calcium halophosphate. [4][5][6] Using this emission center, we reported high quantum efficiency (QE) of SnO-ZnO-P 2 O 5 (SZP) bulk glass, which is the highest QE value of REfree oxide glass (over 80%). 7,8 In addition, we have also demonstrated the UV-excited white light emission property of MnO-doped SZP glasses.…”
