Surface Forms

self-luminous positive

Morphology

self-luminous = luminous (transparent) = self + luminous

The adjective is clearly formed by adding the productive prefix 'self-' to 'luminous', so the meaning 'emitting light by itself' is directly inferable.

Etymology

The word self-luminous is made of self- meaning 'by itself' and luminous meaning 'giving light', like in illuminate. So a self-luminous thing 'gives its own light' instead of just reflecting light.
