— Wet chemical treatments have been performed on phosphor particles. ZnO: Zn phosphor was reductively etched with a basic aqueous solution of sodium borohydride. The etch resulted in a two‐fold increase in the cathodoluminescent efficiency without any detected change in particle size or surface composition as detected by Auger electron spectroscopy. The low‐voltage cathodoluminescent characteristics are particularly enhanced. The enhanced efficiency of the phosphor particles may be attributable to a change in surface structure or an increase in the surface coverage of luminescent centers induced by the reductive etch.
