# Photo Luminescence of SiC

| Siemens actually made and sold a a SiC based LED around 1975 that emitted bluish light. It was not a success and was quickly abandoned. A few year after (the Internet had not yet been invented) it was completely forgotten and it seems to be very difficult to impossible to unearth any documentation to this very first blue LED of humankind
