METAL OXIDE NANOPARTICLES SURFACE-TREATED WITH METAL ION, QUANTUM DOT-LIGHT-EMITTING DEVICE COMPRISING THE SAME AND METHOD FOR FABRICATING THE SAME

摘要

The metal oxide nanoparticle includes a Zn-containing metal Me¹ oxide nanoparticle of Zn_1-xMe¹_xO(0≤x≤0.5) composition, and a metal Me² ion surface treatment layer formed on a surface of the nanoparticle. Here, the metal Me¹ is any one selected from Li, Be, Na, Mg, Al, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Ga, Ge, Rb, Sr, Zr, Nb, Mo, Ru, Rh, Pd, Ag, In, Sn, Sb, Ba and a combination thereof, and the metal Me² is any one selected from Li, Be, Na, Mg, Al, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Rb, Sr, Zr, Nb, Mo, Ru, Rh, Pd, Ag, In, Sn, Sb, Ba and a combination thereof.
