Sulphur-doped graphene quantum dots (S-GQDs) were prepared in this work by a novel and facile method using the co-combustion (T-X-J method) of a liquid mixture of paraffin oil and carbon disulphide (CS 2 ). Ultra-high performance ( R : 307 A W −1 ; D *: 1.5 × 10 14 Jones) ultraviolet photodetectors...
