METHOD FOR CREATING HIGHLY EFFECTIVE UPCONVERSION LUMINESCENCE OF YTTERBIUM OXIDE COMPLEXES WITH GOLD NANOPARTICLES Russian patent published in 2022 - IPC C09K11/58 C09K11/77 B82Y40/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for creating highly effective upconversion luminescence of ytterbium oxide complexes with gold nanoparticles. Method includes producing a powder of ytterbium oxide Yb₂O₃ from metal ytterbium; adding a colloidal solution of ablative gold nanoparticles thereto, produced by the method for femtosecond laser ablation in liquid; drying the resulting composition, forming a tablet and placing under 980 nm laser radiation, resulting in a red glow of upconversion luminescence.

EFFECT: possibility of creating a red glow of upconversion material under the impact of 980 nm laser radiation, allowing converting subvisible IR radiation into visible.
