Abstract:
The invention relates to a method which comprises in at least one embodiment of the method the following steps: A) producing radiation-active islands (4) having a semiconductor layer sequence (3) on a growth substrate (2), wherein the islands (4) each have at least one active zone (33) of the semiconductor layer sequence (3) and an average diameter of the islands (4), as viewed in a top view of the growth substrate, is in a range from 50 nm to 10 μm inclusive, B) producing a separating layer (5) on a side of the islands (4) facing the growth substrate (2), wherein the separating layer (5) surrounds the islands (4) all around, as viewed in a top view of the growth substrate (2), C) attaching a carrier substrate (6) to a side of the islands (4) facing away from the growth substrate (2), and D) detaching the growth substrate (2) from the islands (4), wherein at least a part of the separating layer (5) is destroyed and/or at least temporarily softened during the detachment.
Abstract:
The invention relates to a method for measuring light radiation (300) emitted by a light-emitting diode (210). In the method, an end (121) of an optical fiber (120), which optical fiber is connected to a measuring apparatus (130), is irradiated with the light radiation (300) emitted by the light-emitting diode (210) through an optical apparatus (140), such that part of the light radiation (300) is coupled into the optical fiber (120) and conducted to the measuring apparatus (130). The optical apparatus (140) causes the light radiation (300) passing through the optical apparatus (140) to be emitted in diffuse form in the direction of the end (121) of the optical fiber (130). The invention further relates to a device (100) for measuring light radiation (300) emitted by a light-emitting diode (210).
