Nature Communications, 2021 AbstractFor the first time, lasing at NV−centers in an optically pumped diamond sample is achieved. A nanosecond train of 150-ps 532-nm laser pulses was used to pump the sample. The lasing pulses have central wavelength at 720 nm with a spectrum width of 20 nm, 1-ns duration and total energy around 10 nJ.

Synthesis of paracrystalline diamond
Nature, 2021 Solids in nature can be generally classified into crystalline and non-crystalline states1–7, depending on whether long-range lattice periodicity is present in the material. The differentiation of the two states, however, could face fundamental challenges

Surface transfer doping of diamond: A review
Progress in Surface Science, 2021 Ultra-wide bandgap materials show great promise as a solution to some of the limitations of current state of the art semiconductor technology. Among these, diamond has exhibited great potential for use in high-power, high-temperature electronics, as well

Diamond quantum thermometry: from foundations to applications [PDF]
Nanotechnology, 2021 Diamond quantum thermometry exploits the optical and electrical spin properties of colour defect centres in diamonds and, acts as a quantum sensing method exhibiting ultrahigh precision and robustness. Compared to the existing luminescent nanothermometry

Beilstein Journal of Nanotechnology, 2012 We demonstrate the coupling of single color centers in diamond to plasmonic and dielectric photonic structures to realize novel nanophotonic devices. Nanometer spatial control in the creation of single color centers in diamond is achieved by implantation of nitrogen atoms through high-aspect-ratio channels in a mica mask.

First principles calculation of lithium-phosphorus co-doped diamond [PDF]
, 2013 We calculate the density of states (DOS) and the Mulliken population of the diamond and the co-doped diamonds with different concentrations of lithium (Li) and phosphorus (P) by the method of the density functional theory, and analyze the bonding ...
