1. A nanoparticle, comprising: a nanometer particle, and a first ligand coordinated on a surface of the nanometer particle; wherein
under irradiation of ultraviolet light, the nanometer particle is configured to absorb photons to generate electrons in an excited state, and the electrons are delocalized to the surface of the nanometer particle to be in contact with the first ligand; and
under an action of a transfer reaction of the electrons, a cross-linking reaction occurs among first ligands of adjacent nanoparticles.
