Description

We have development alpha dust monitor with a red or infrared emitting scintillators, and the scintillation properties were investigated for Ce:Y₃(Mg_x Al_5-2x Si_x)O₁₂ (x=0.0, 0.5, 2.0) crystals were grown by the micro-pulling-down method.Ce-doped Y₃(Mg₂ Al Si₂)O₁₂ had an emission wavelength of 620 nm, and the red-shift of emission bands was observed for Mg and Si-admixed samples due to changing lattice constants compared to the Mg and Si free sample.
