“…Thus, the decay kinetics of the UV emissions of LuAG:Bi and YAG:Bi is similar to that observed for the triplet emission of Bi 3+ centers in some other hosts (see, e.g., [1,[9][10][11]). It can be described within the phenomenological model used in [1] for Bi 3+ centers in Y 3 Ga 5 O 12 .…”

Single crystalline films (SCFs) of Y 3 Al 5 O 12 :Bi and Lu 3 Al 5 O 12 :Bi with different Bi 3+ contents are studied at 1.7-300 K by the time-resolved luminescence spectroscopy methods under excitation in the 2.4-20 eV energy range. Two ultraviolet emission bands of these SCFs, located at 3.99-4.08 eV at T<80 K and at 4.11-4.19 eV at 150 K, arise from the radiative decay of the metastable and radiative minima, respectively, of the triplet relaxed excited state (RES) of a single Bi 3+ center, which are related to the 3 P 0 and 3 P 1 levels of a free Bi 3+ ion. Their excitation bands located around 4.6 eV, 5.2 eV, and 5.95 eV are assigned to the 1 S 0 → 3 P 1 , 1 S 0 → 3 P 2 , and 1 S 0 → 1 P 1 transitions, respectively, in free Bi 3+ ions. The luminescence of dimer Bi 3+ -Bi 3+ centers is not detected in the SCFs studied. The lower-energy (2.6 eV) visible emission of these SCFs is due to an exciton, localized near a single Bi 3+ ion, while the higherenergy (2.75 eV) visible emission, an exciton, localized near a dimer Bi 3+ -Bi 3+ center. Temperature dependences of the luminescence decay times are measured for the ultraviolet and visible emissions in the 1.7-300 K temperature range and simulated by phenomenological models of the dynamics of corresponding excited states. The quantitative parameters of RESs (the energy separations between the energy levels and the rates of the radiative and nonradiative transitions from these levels) are calculated.

“…Comparison of the data obtained for YAG:Bi in the present paper and for LuAG:Bi by Babin et al (2009) with those reported for the UV emission of Bi 3þ centers in other hosts (see, e.g., Wolfert and Blasse, 1985;Donker et al, 1989;Aceves et al, 1996;Nikl et al, 2005) allows us to conclude that the 5.9 eV and 4.57 eV excitation bands arise from the electronic transitions to the singlet and The intensity of the UV band is decreased 10 times. The spectra are distorted around 2.7 eV due to the contamination of the samples with Ce 3þ ions and the reabsorption of the VIS emission in the z2.7 eV absorption band of Ce 3þ centers.…”

a b s t r a c tSingle crystalline films of Lu 3 Al 5 O 12 :Bi and Y 3 Al 5 O 12 :Bi have been studied at 4.2-450 K by the timeresolved luminescence spectroscopy method. Their emission spectrum consists of two types of bands with strongly different characteristics. The ultraviolet band consists of two components, arising from the electronic transitions which correspond to the 3 P 1 / 1 S 0 and 3 P 0 / 1 S 0 transitions in a free Bi 3þ ion. At T < 80 K, mainly the lower-energy component with the decay time w10 À3 s is observed, arising from the metastable 3 P 0 level. At T > 150 K, the higher-energy component prevails, arising from the thermally populated emitting 3 P 1 level. The visible emission spectrum consists of two dominant strongly overlapped broad bands with large Stokes shifts. At 4.2 K, their decay times are w10 À5 s and w10 À4 s and decrease with increasing temperature. Both of the visible emission bands are assumed to be of an exciton origin. The lower-energy band is ascribed to an exciton, localized near a single Bi 3þ ion. The higherenergy band, showing a stronger intensity dependence on the Bi 3þ content, is assumed to arise from an exciton, localized near a dimer Bi 3þ center. The structure of the corresponding excited states is considered, and the processes, taking place in these states, are discussed.

“…At higher temperatures, the decay time decreases due to the luminescence thermal quenching. Analogous τSC(T) dependences were obtained, e.g., for the triplet emission of Pb 2+ centers in alkali halides [131] and Bi 3+ centers in CaO [85], alkaline-earth sulfides [87], and alkaline-earth fluorides [92]. Emission spectra (normalized) of Lu3Al5O12:Bi and Y3Al5O12:Bi measured at 80 K under different excitations shown in the legends.…”

Luminescence Spectroscopy and Origin of Luminescence Centers in Bi-Doped Materials

Bi-doped compounds recently became the subject of an extensive research due to their possible applications as scintillator and phosphor materials. The oxides co-doped with Bi3+ and trivalent rare-earth ions were proposed as prospective phosphors for white light-emitting diodes and quantum cutting down-converting materials applicable for enhancement of silicon solar cells. Luminescence characteristics of different Bi3+-doped materials were found to be strongly different and ascribed to electronic transitions from the excited levels of a Bi3+ ion to its ground state, charge-transfer transitions, Bi3+ dimers or clusters, radiative decay of Bi3+-related localized or trapped excitons, etc. In this review, we compare the characteristics of the Bi3+-related luminescence in various compounds; discuss the possible origin of the corresponding luminescence centers as well as the processes resulting in their luminescence; consider the phenomenological models proposed to describe the excited-state dynamics of the Bi3+-related centers and determine the structure and parameters of their relaxed excited states; address an influence of different interactions (e.g., spin-orbit, electron-phonon, hyperfine) as well as the Bi3+ ion charge and volume compensating defects on the luminescence characteristics. The Bi-related luminescence arising from lower charge states (namely, Bi2+, Bi+, Bi0) is also reviewed.
