COLOR TUNABLE MULTIFUNCTIONAL NANOPHOSPHOR, SYNTHESIS METHOD THEREOF, AND POLYMER COMPOSITE INCLUDING THE NANOPHOSPHOR

摘要

A nanophosphor according to one embodiment of the present invention includes at least one selected from a group consisting of Tb^3+, Eu^3+, and a combination thereof; and fluoride-based nanoparticles co-doped with Ce^3+. The nanophosphor is excited by ultraviolet light of a single wavelength and can emit green, yellow, orange, and red light. The nanophosphor has no flickering phenomenon and improves light stability. The nanophosphor can be utilized as a bio-imaging contrast agent, a transparent display device, an anti-counterfeit code, and the like.
