    摘要: In at least one embodiment of the optoelectronic semiconductor chip (1), the latter is based on a nitride material system and comprises at least one active quantum well (2). The at least one active quantum well (2) is designed to generate electromagnetic radiation when in operation. Furthermore, the at least one active quantum well (2) comprises N successive zones (A) in a direction parallel to a growth direction z of the semiconductor chip (1), N being a natural number greater than or equal to 2. At least two of the zones (A) of the active quantum well (2) have mutually different average indium contents c. Furthermore the at least one active quantum well (2) fulfils the condition: 40≦∫c(z)dz−2.5N−1.5∫dz≦80
