The present invention relates to a luminescent rare earth compound and dichroism fluorescent composition thereof, and more particularly, the luminescent rare earth compound is a luminescent rare earth compound excited by shortwave UV (Ultra-Violet). The luminescent rare earth compound and/or products applied with the luminescent rare earth compound according to the present invention can emit strong red and green colors by being excited at 240-330 nm range of wavelengths, while not being excited at 360-380 nm range of wavelengths, and showing no colors under visible light. Furthermore, the compound may be variably utilized to printed materials and plastic mold products because of possessing high heat resistance, high light resistance and high dispersibility of medium light. In addition, compositions emitting respectively different colors at mutually different wavelength ranges can be provided by mixing the luminescent rare earth compound according to the present invention with other excited luminescent compounds.

The present invention relates to a near-ultraviolet stimulated light-emitting compound, and more specifically relates to a fluorescent quinazolinone compound which is stimulated in the near ultraviolet region. The fluorescent quinazolinone compound according to the present invention is colorless in daylight but exhibits a high fluorescent intensity when irradiated with light in the near ultraviolet region. Also, the fluorescent quinazolinone compound can be easily used with printed and plastic molded products since the compound not only has a high degree of light fastness and thermal stability but also high dispersibility.
