Oxide-based quantum cutter method and phosphor system |
摘要 |
A method of producing two visible light photons from an oxide-based phosphor doped with praseodymium (Pr) and including atoms of at least one activator in response to excitation with a single ultraviolet light photon. The method includes exciting the Pr of the oxide-based phosphor with a photon of ultraviolet light to excite an electron to an excited state, the excited electron falling to a lower energy state in a non-radiative transition and transferring energy to excite a first activator atom in the oxide-based phosphor, the first activator atom emitting a first photon of visible light, and the excited electron falling further to a lower energy state in a non-radiative transition, transferring energy to excite a second activator atom in the oxide-based phosphor, the second activator atom emitting a second photon of visible light. An oxide-based phosphor doped with praseodymium includes atoms of at least one activator and emitting two visible light photons in response to excitation by a single ultraviolet light photon.
