Abstract
A quantum dot luminophore comprising at least one luminescent core, a spacer layer, an encapsulation layer, and a plurality of quantum dots is disclosed. The luminescent core is designed to emit a red light after being excited by an incident blue light, and the quantum dots are configured to irradiate a green light by the illumination of the blue light and/or the red light. In the present invention, the quantum dots are particularly used to cover or surround the luminescent core for solving the light re-absorption. By such arrangement, even though part of incident blue light (about 10-30%) may be reflected by the luminescent core made of phosphor materials, the reflected blue light still can also be recycled by the quantum dots surrounding the luminescent core, such that the light conversion efficiency and emission intensity of the luminescent core are hence increased because the loss of blue light is decreased.
