Cathodo- and radioluminescence of Tm${}^{3+}$:YAG and Nd${}^{3+}$:YAG in an extended wavelength range

Abstract

We have studied the cathodo- and radioluminescence of Nd:YAG and of Tm:YAG single crystals in an extended wavelength range up to $\approx 5\mu$m 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 $\approx 10^4$photons/MeV, in good agreement with literature results, in the infrared range we have found a light yield $\approx 5\times 10^4$photons/MeV, thereby proving that ionizing radiation is particularly efficient in populating the low lying levels of rare earth doped crystals.
