Abstract
An object is to provide a composition that contains a phosphorus-containing carbon quantum dot and can efficiently emit relatively long wavelength light. The composition to achieve the above object contains: a phosphorus-containing carbon quantum dot containing phosphorus as a heteroatom; and a smectite.
Claims2
A method of producing a composition, the method comprising:
- preparing a solid mixture of a solid organic compound having a reactive group, a solid phosphorus compound, and a solid smectite;
- and
- heating the mixture in a solid state to obtain a composition containing:
- a phosphorus-containing carbon quantum dot containing phosphorus as a heteroatom, and
- a smectite.
