Dose Rate Response of LaMgAl11O19 Doped with Various Rare-earth Ions with NIR Luminescence
The radioluminescence and dose rate response of LaMgAl 11 O 19 doped with rare earth single crystals were investigated.All the samples showed emission peaks at wavelengths longer than 800 nm corresponding to doped trivalent rare-earth ions.Among the prepared samples, the Nddoped sample showed the best lower detection limit of 1.6 mGy/h, enabling highly sensitive dose measurement.
