Point defects in semi-conductors are renowned for single photon emission apart from having important implications on optical and transport properties of their host crystal. Various two dimensional Van der Waals (2D) crystals can provide a plethora of defects  and have revolutionized scientific research with unique phenomena related to their reduced dimensional. We summarize optical investigations of localized quantum emitters in 2D semi-conductors with sub band-gap excitation energizes, emphasizing those in hexagonal boron nitride that exhibit para-magnetic responses to applied external magnetic fields.
