— Y 2 O 3 :Eu 3+ has been extensively investigated as a red phosphor for fluorescent lamps and color displays. In particular, there have recently been several studies examining the effect of impurities on the luminescence efficiency for Y 2 O 3 :Eu 3+ under UV excitation. In this work we investigate the effects of codoping Y 2 O 3 :Eu 3+ with Ca 2+ and Zr 4+ on the emission produced by cathode‐ray excitation. Specifically, we have measured the relative efficiency, fluorescent lifetimes, and fluorescent spectra under cathode‐ray excitation and compare these results to those previously observed under UV excitation.
