Luminescent core/shell nanoparticles |
摘要 |
The present invention relates to Luminescent nanoparticles comprising (a) a core made from a luminescent metal salt selected from phosphates, sulfates or fluorides, being surrounded by (b) a shell made from a metal salt or oxide capable of preventing or reducing energy transfer from the core after its electronic excitation to the surface of the nanoparticle, e.g. a shell made from a non-luminescent metal salt or oxide, which are characterized by higher quantum yields and can be used in various fields including light generation and security marking.
