Surface Forms

photoemissive positive

Morphology

photoemissive = emissive (semi-transparent) = photo + emit + ive

The word is transparently built from photo- + emissive, but the technical meaning and the stem change from emit to emissive make it only partly transparent.

Etymology

Photoemissive combines photo- ('light') and emit ('to send out'), with photo- as in photograph and emit like when something gives off a sound. So a photoemissive material 'sends out' tiny electric particles called electrons when light hits it.
