The present invention relates to a luminescent rare earth element compound and a dichroic phosphor composition containing the same and, more specifically, the luminescent rare earth element compound is a luminescent rare earth element compound to be excited by short-wavelength ultraviolet rays. The luminescent rare earth element compound according to the present invention and/or a product to which the compound is applied is non-luminescent under visible rays, and is not excited in the wavelength of the range of 360-380 nm and is excited in the wavelength of the range of 240-330 nm, and thus exhibits strong red and green luminescence. In addition, the compound has high heat resistance and light resistance and high dispersion of medium light, and thus can be variously applied to a printed product or a plastic molded product. Additionally, a composition respectively emitting different colors in different wavelength ranges can be provided by mixing the luminescent rare earth element compound according to the present invention and other excited luminescent compounds. |
