Based on luminophore combination being close to diamond in luminescence parameters, water-organic emulsions were synthesized that modified spectral-kinetic characteristics of low-luminescent diamond crystals. The combination of luminophores was used, including an organic luminophore, anthracene, and inorganic luminophore, K-35, the spectral and kinetic characteristics of which make it possible to achieve the required luminescence values of diamonds and ensure their maximum extraction in existing diamond-containing kimberlite X-ray separation process flows. Non-polar hydrocarbons were experimentally substantiated as an organic medium for the luminophores. Mathematical processing of the obtained results was performed and relationships between the composition of the luminophore combination and kinetic characteristics of the luminescent response were determined.
