    摘要: A luminescent material is disclosed. The luminescent material may include a first compound having a host lattice comprising first ions and oxygen. A first portion of the first ions may be substituted by copper ions. In one embodiment, the host lattice may include silicon, the copper ions may be divalent copper ions and the first compound may have an Olivine crystal structure, β-K0.2SO4 crystal structure, a trigonal Glaserite (K3Na(SO4)2) or monoclinic Merwinite crystal structure, a tetragonal Ackermanite crystal structure, a tetragonal crystal structure or an orthorhombic crystal structure. In another embodiment, the copper ions do not act as luminescent ions upon excitation with the ultraviolet or visible light.

    摘要: A light emitting device is disclosed. The light emitting device may include a light emitting diode (LED) for emitting light and a phosphor adjacent to the LED. The phosphor may be excitable by light emitted by the LED and may include a first compound having a host lattice comprising first ions and oxygen. In one embodiment, the host lattice may include silicon, the copper ions may be divalent copper ions and the first compound may have an Olivin crystal structure, a β-K2SO4 crystal structure, a trigonal Glaserite (K3Na(SO4)2) or monoclinic Merwinite crystal structure, a tetragonal Ackermanite crystal structure, a tetragonal crystal structure or an orthorhombic crystal structure. In another embodiment, the copper ions do not act as luminescent ions upon excitation with the light emitted by the LED.
