Nature, 2020 Self-assembling colloidal particles in the cubic diamond crystal structure could potentially be used to make materials with a photonic bandgap1-3. Such materials are beneficial because they suppress spontaneous emission of light1 and are valued for their applications as optical waveguides, filters and laser resonators4, for improving light-harvesting ...

Sensitivity optimization for NV-diamond magnetometry [PDF]
, 2019 Solid-state spin systems including nitrogen-vacancy (NV) centers in diamond constitute an increasingly favored quantum sensing platform. However, present NV ensemble devices exhibit sensitivities orders of magnitude away from theoretical limits.

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
