Abstract
(Y,Gd)B0₃:Eu³+ is the red phosphor in plasma displays and mercury free lamps. In this work the non-radiative host to activator energy transfer efficiency of YB0₃ :Eu³⁺ is being compared to that of (Y,Gd)B0₃ :Eu³+. Energy transfer efficiency is determined by taking excitation and reflectance spectra under vacuum ultraviolet (VUV) excitation. It is well known that co-doping YB0₃: Eu³+ with gadolinium increases the emission intensity. This research has determined that the addition of gadolinium increases the transfer efficiency.
