Y3Al5O12:Ce efficiencies (photons emitted per incident photon) as a function of excitation energy in forward and backward modes for 1.33 (⋄ and ×), 3.37 (+ and ○) and 20.56 mg cm−2 (▵ and ♦) screens at 45°. Error bars are shown for two cases. Backward mode efficiencies between 20 and 80 eV for the 20.56 mg cm−2 screen are expanded. |
