摘要

Luminescent diode with high luminosity comprises a rear electrode (10); a semiconductor substrate (12) formed on the rear electrode; a lower sleeve layer (140) of first conductivity on the substrate; an active layer (142) on the lower sleeve layer; an upper sleeve layer (144) of second conductivity on the active layer; a window layer (16) of second conductivity on the upper sleeve layer; a contact layer (17) on the first part of the window layer; a conductive transparent layer (19); and a front electrode (20) on the transparent layer.
