Photoluminescence, scintillation, and dosimetric properties of Tb-doped Mg2SiO4 single crystals

Analysis of Photoluminescence and Dosimetric Properties of (Ce, Tb)-codoped Magnesium Orthosilicate Single Crystals

“…Both samples had peaks at 380, 420, 440, 460, 480, 495, 550, 590, and 630 nm, which are typical wavelengths due to the 4f-4f transitions of Tb 3+ ions. (28) In contrast, no peaks due to the 5d-4f transitions of Ce 3+ ions were detected, whereas the PL properties suggested the existence of Ce 3+ ions. Thus, it is considered that Ce 3+ ions did not directly contribute to the TSL process as luminescence centers.…”

“…These emissions originated from the 4f-4f transitions of Tb 3+ ions. (28) On the other hand, in the x = 0.01 sample, emission peaks due to 4f-4f transitions of Tb 3 + ions were observed under excitation at wavelengths of 250, 340, and 370 nm. Furthermore, a broad emission band was observed from 370 to 540 nm under excitation at 340 and 370 nm.…”

“…Moreover, emission peaks at around 550 nm were also detected under excitation at 370 nm. These emissions originated from the 4f-4f transitions of Tb 3+ ions (28). On the other hand, in the x = 0.01 sample, emission peaks due to 4f-4f transitions of Tb 3 + ions…”

Photoluminescence, scintillation, and dosimetric properties of undoped and Tb-doped Ba3Gd(PO4)3 single crystals

“…Therefore, numerous dosimetric materials doped with Tb 3+ ions have been studied, including the commercial TSL dosimeters, Mg 2 SiO 4 . [22][23][24][25][26][27] Hence, based on the above matters, Tb-doped BGPO can be a potential candidate of novel dosimetric materials.…”

Visible–Near Infrared Scintillation Properties of Er-Doped Bi4Si3O12 Single Crystals

“…5 Since the performance of the scintillation detectors depends on that of the scintillators, many researchers have actively developed novel scintillators in order to pursue higher performance in radiation detection. [6][7][8][9] For such applications, the developments of the scintillators have mainly been conducted with the materials which emit photons in the ranges of ultraviolet (UV)-visible (Vis). 6,[10][11][12][13][14][15][16][17] This reason is that photomultiplier tube (PMT), which has been the common photodetector for scintillation detectors, has the wavelength sensitivity in the ranges of UV-Vis.…”
