Hexagonal boron nitride (h-BN) as a wide-bandgap van der Waals material has been considered intensively by the scientific community due to its exciting chemical, optical, electronic, and mechanical properties. The recent observation of room temperature single photon emission from h-BN defect centers makes it also an attractive material platform for applications of quantum photonics. Single-photon sources play an essential role in various quantum technologies such as quantum computing, quantum sensing, and quantum telecommunication. Quantum emitters in h-BN have been investigated extensively in recent years due to their exciting properties such as high brightness at room temperature,
high stability, and spectral tunability. In the first part of this talk, I will present the low-temperature photophysical studies of h-BN quantum emitters and discuss the various aspects of light emission in addition to its quantum nature. In the second part of the talk, I will talk about our recent work focusing on the magnetic field dependency of the PL emission of quantum emitters at liquid helium temperature. The interesting phenomena of photodarkening observed in the PL emission will be discussed.
