Crystal growth of La2Zr2O7 by micro-pulling-down method using Mo and W crucibles

Crystal growth, luminescence, and scintillation properties of Er-doped La2Hf2O7 single crystal

“…The W-crucible, which has a higher mp than Ir, has made it possible to grow functional single crystals with a high mp of over 2200 °C. 19,20) Thus, LHO single crystals were successfully grown from the melt in a W-crucible.…”

“…Er 3+ ions in luminescent and scintillator materials have been widely studied in previous reports. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] Their emissions, which originate from the 4 I 13/2 -4 I 15/2 be observed in the IR region. If emissions in the IR region can be realized in LHO single crystals with high potential, it is expected to be developed into some devices for applications such as communication and observation using IR light.…”
