Spectroscopic and neutron detection properties of rare earth and titanium doped LiAlO2 single crystals

Optical, scintillation and radiation tolerance properties of Pr-doped pyrosilicate crystals

“…No scintillators available today can fulfill all the requirements so a continuous effort has been paid to develop new scintillator materials in many material forms including single crystals, ceramics, and glasses. [11][12][13][14][15][16][17][18][19][20][21][22] Among scintillators developed up to now, rare earth ions commonly play an important role as a luminescence center, and the most common luminescence centers are Ce 3+ , 14) Pr 3+ , 22) and Eu 2+ 16) for scintillators since they show a high light yield and a short decay time due to the 5d-4f transitions. 23) Among these rare earth ions, Pr 3+ has attracted much interest since it shows a fast scintillation decay around 10-20 ns [24][25][26] with an efficient light yield.…”

Titanium-doped LiAlO2 ceramics for neutron scintillation

“…LiAlO2, in particular, is a non-hydroscopic material with a high lithium content and low density. It has been investigated as a tritium breeding material for fusion reactors [10,11], a substrate for the epitaxial growth of GaN [12,13], a ceramic filler for lithium-ion polymer batteries [14], an electrolyte matrix for molten carbon fuel cells [15] or as an optical material when doped with transition metal or lanthanide ions [16][17][18][19]. The most stable modification is the tetragonal γ-phase, in which Li + and Al 3+ ions are tetrahedrally coordinated; the calculated density is 2.615 g/cm 3 [20].…”
