| 简介 |
The present invention refers to ultraviolet light or visible light as pertains to light emitting materials for VUV excitation, which contains an rare earth, lead and/or containing copper with an using compounds is characterised in that it has a. Compounds, light emitting element for absorption of part of light emitted from the diode to prevent the light and emits lights of different wavelengths, aluminate, and europium-containing silicate-based, excitation, a rare (Germanate) and/or a rare-(Germanate-silicate)-based, and array compounds of one or more compounds to mix the. configurable. According to is, light emitting emits light different wavelength from compound absorbs some light emitted from light having luminescent materials containing and copper is provided. The such that the light-generating substances present, rendering properties excellent the medium varies the degree of the generation of heat and lengthen, water, moisture, , solvent, and a polar solvent provides Ni as a metal precursor. |
