LUMINESCENT DIAMOND WITH NEGATIVELY CHARGED VACANCIES

Luminescent materials have red luminescent behavior after sintering using an HPHT process. Red luminescence is achieved with a temperature of 1475 °C to 1800 °C, and potentially 1600 °C to 1750 °C, with coarse sintered diamond powder having an average size greater than or equal to 100 nm, or more fi...

Zusammenfassung:	Luminescent materials have red luminescent behavior after sintering using an HPHT process. Red luminescence is achieved with a temperature of 1475 °C to 1800 °C, and potentially 1600 °C to 1750 °C, with coarse sintered diamond powder having an average size greater than or equal to 100 nm, or more fine grain average grain sizes of at least 25 nm or at least 50 nm. The luminescent material has red luminescence as a result of NV
