OPTICALLY TRANSPARENT LUMINESCENT NANOSTRUCTURED CERAMIC MATERIAL Russian patent published in 2021 - IPC C04B35/443 C09K11/08 B82Y40/00 

FIELD: optoelectronics and laser technology.

SUBSTANCE: invention relates to the field of creating optically transparent luminescent nanostructured ceramic materials based on aluminum-magnesium spinel (MgAl₂O₄) and can be used as a functional material for photonic devices, optoelectronics and laser technology. An optically transparent luminescent nanostructured ceramic material based on a matrix of aluminum-magnesium spinel containing aluminum oxide is proposed, characterized in that the matrix of aluminum-magnesium spinel additionally contains carbon in the form of graphene plates 3-10 nm in size with the following mass ratio of components, %: aluminum-magnesium spinel (MgAl₂O₄) 99.3-99.49; aluminum oxide (Al₂O₃) 0.4-0.5; carbon (C) 0.01-0.3. Aluminum-magnesium spinel and aluminum oxide are in a nanostructured state with a coherent scattering region of 5–40 nm.

EFFECT: material has a tunable photoluminescent range, which will make it possible to use it in LED devices, plasma display panels, tunable detectors of the UV-visible spectral range, light matrix indicators.
