Diamond is a host for a wide variety of colour centres that have demonstratedoutstanding optical and spin properties. Among them, the nitrogen-vacancy (NV)centre is by far the most investigated owing to its superior characteristics,which promise the development of highly sophisticated quantum devices, inparticular for sensing applications. Nevertheless, harnessing the potential ofthese centres mainly relies on the availability of high quality and puritydiamond single crystals that need to be specially designed and engineered forthis purpose. The plasma assisted Chemical Vapour Deposition (CVD) has become akey enabling technology in this field of research. Nitrogen can indeed bedirectly in-situ doped into a high crystalline quality diamond matrix in acontrolled way allowing the production of single isolated centres or ensemblesthat can potentially be integrated into a device. In this paper we will providean overview on the requirements for synthesizing quantum-grade diamond films byCVD. These include the reduction of impurities and surrounding spins that limitcoherence times, the control of NV density in a wide range of concentrations aswell as their spatial localization within the diamond. Enhancing the chargestate and preferential orientation of the colour centres is also discussed.These improvements in material fabrication have contributed to position diamondas one of the most promising solid-state quantum system and the firstindustrial applications in sensing are just starting to emerge.
