  • Fluorescent layer and its preparation method and uses
    Patent number: 8836207
    Abstract: A fluorescent layer, its preparation method and uses are provided. The fluorescent layer is provided from a fluorescent material and a calcining material. The fluorescent material is in an amount ranging from about 5 wt % to about 95 wt % based on the total weight of the fluorescent layer. The fluorescent layer of the present invention can be used in a light-emitting diode to change the color of emitting-light and improve the heat dissipation of the light-emitting diode. Furthermore, the fluorescent layer of the present invention is free of an organic resin, and thus, does not have the problem of aging (etiolation). The final product has a stable, lasting and durable luminescent quality.
