There is a great potential in the development of versatile single‐photon devices based on nitride‐based single quantum dots due to their unique properties. Their emission can be engineered to span a wide spectral range from the ultraviolet to the blue and green regions of the spectrum which may prove important for several applications such as free‐space quantum cryptography and low‐noise absorption measurements. It is also possible to dynamically tune the wavelength of the emitted single photons over a wide range by controlling the internal piezoelectric field using externally applied electric fields. The nitrides also have the potential of providing devices which operate at relatively high temperatures. In this contribution, we review the progress made so far towards the development of optically excited and electrically driven single photon sources based on these structures.
