  Two dimensional systems offer a unique platform to study light matter
interaction at the nanoscale. In this work we report on robust quantum emitters
fabricated by thermal oxidation of tungsten disulphide multilayers. The
emitters show robust, optically stable, linearly polarized luminescence at room
temperature, can be modeled using a three level system, and exhibit moderate
bunching. Overall, our results provide important insights into understanding of
defect formation and quantum emitter activation in 2D materials.
