We report photoluminescence studies of micro- and nano-sized diamonds with NV0, NV- and SiV- centers under hydrostatic pressure up to 50 GPa. Diamonds have been obtained by high-pressure high-temperature (HPHT) treatment of metal-free growth systems based on mixtures of hydrocarbon, fluorocarbon, and silicone-containing organic compounds.
Keywords: diamond, colour centres, high pressures, DAC.
