Luminescence of RbI: Tl

Decay kinetics of the luminescence of Ag– centers doped in alkali halide crystals

“…For example, several luminescence bands are observed owing to the non-radiative transitions between the 3 T 1u , 3 T 2u + 3 E u , and 1 T 1u APESs [6][7][8]. Though the luminescence properties including polarization characteristics have been extensively investigated [9][10][11][12][13][14], a lot of studies on the luminescence properties have been performed under the excitation on the A absorption band, especially the studies on the decay kinetics of the luminescence [11][12][13][14][15][16][17][18][19][20][21][22], because of the complex luminescence properties under the excitation on the C absorption band.…”

“…When the absorption bands are excited, the luminescence bands due to the radiative transition from the minima on the adiabatic potential energy surfaces (APESs) of the 3 T 1u , 3 T 2u + 3 E u , and 1 T 1u excited states appear with Stokes shifts [2][3][4][5][6][7][8]. These luminescence bands are called the A′, B′, and C′ luminescence, respectively.…”

Tl-concentration dependence of scintillation properties in Tl-doped CsBr single crystals

“…In most of the Tl-doped alkali halides, the emission wavelength in the range of UV to visible is suitable for wavelength sensitivity of common PMTs. [29][30][31][32][33][34][35][36][37] In addition, the decay times are from several hundred ns to a few μs, which is acceptable for photon-counting applications. 38,39) Most of the previous studies focused on iodides, and there have been few reports on bromides and chlorides.…”
