Radioluminescence emission of YAG:RE laser-sintered ceramics

Ho3+ codoping of GGAG:Ce: a detailed analysis of acceleration of scintillation response and scintillation efficiency loss

“…However, as shown in our previous studies for Er 3+ , 1,2 Dy 3+ , 3 and Nd 3+ (ref. 4) and studies of other authors for Sm 3+ , 12 Eu 3+ and Tb 3+ , 13 and Tm 3+ (ref. 14) unlike Ho 3+ all of them have parity-forbidden 4f → 4f emission positioned in the range of Ce 3+ emission which would introduce slow components into detectable emission when using common photomultipliers or even Si-based semiconductor photodetectors.…”

Fabrication of ceramic scintillators by laser sintering: the case of Lu3Al5O12:Pr

“…The intrinsic scintillator Bi 4 Ge 3 O 12 (BGO) was the first to be fabricated by laser sintering. [2][3][4] Later, doped phosphors were also fabricated, including Y 2 O 3 5) and Y 3 Al 5 O 5 (YAG), [6][7][8][9][10] concomitant to an intense effort focused on aluminate-based persistent phosphors. [11][12][13][14][15] Overall, high densities, typically ⩾95% of the theoretical density were obtained, the achievement of optical transparency remains a challenge.…”
