We have studied the cathodo- and radioluminescence of Nd:YAG and of Tm:YAG single crystals in an extended wavelength range up to ≈5μm in view of developing a new kind of detector for low-energy, low-rate energy deposition events. Whereas the light yield in the visible range is as large as ≈104photons/MeV, in good agreement with literature results, in the infrared range we have found a light yield ≈5×104photons/MeV, thereby proving that ionizing radiation is particularly efficient in populating the low lying levels of rare earth doped crystals.

Whereas the light yield in the visible range is as large as ≈104photons/MeV, in good agreement with literature results, in the infrared range we have found a light yield ≈5×104photons/MeV, thereby proving that ionizing radiation is particularly efficient in populating the low lying levels of rare earth doped crystals.
