Abstract

The invention provides a photomagnetic functional material of metallofullerene and its preparation method and application. The photomagnetic functional material of metallofullerene is in molecular form, with a size of about 1nm, a definite structure, easy manipulation, and performance It has single-molecule magnet performance and photoluminescence properties, and it has hysteresis phenomenon below 5K, and the metallofullerene containing Er has a luminescence wavelength in the range of 1400-1600nm, and the metallofullerene containing Y has a luminescence wavelength in the range of 700-800nm . Not only that, the photoluminescence wavelength or intensity of the optomagnetic functional material of the metal fullerene has modulation properties under the influence of an external magnetic field, that is, there is a coupling effect between magnetism and light, which can be used for quantum information storage or quantum computing.

Description

technical field

[0001] The invention belongs to the field of molecular materials. Specifically, it belongs to the application field of fullerene functional materials, including a novel photomagnetic functional material of metal fullerene and its preparation and application. Background technique

[0002] Metallofullerenes are a class of nanomaterials that can embed metals in fullerene carbon cages. It has a special structure, and many clusters that cannot exist independently can also exist stably in the fullerene carbon cage, which can embed metal nitrides, bimetals, metal sulfides and metal oxides, etc., so There are many types of metallofullerenes. The carbon cages of metallofullerenes can embed multiple metals, and even embed several different metals through the design of the raw materials. The combination of metals with different functions embedded in the carbon cage, using metallofullerenes as a platform provides new possibilities for the construction of new multifunc...
