An improved microchannel plate structure (10) has microchannels (12) with a wall (14) surface portion (16) having an improved retention of indigenous constituents (i.e., selected elements and/or chemical compounds) which allow the glass to be made electrically active as a secondary-electron emitter. Thus, the microchannels (12) are more electrically active than those of conventional microchannel plates, and an improved electron gain is realized. A method of making a microchannel plate (10) embodying the inventive structure is set out.
