DOI: 10.1088/2053-1591/abda64
Abstract: Photoluminescent thin films of europium doped lutetium oxide (Lu2O3:Eu) -an established material for x-ray scintillators- have been grown on glass substrates employing radio-frequency magnetron sputtering deposition technique. Optically transparent, crystalline films were obtained by only… read more here.
