Quantum rod and method of fabricating the same

A method of fabricating a quantum rod comprising:

• forming a core nanocrystal using semiconductor particle;
• doping a surface of the core nanocrystal with a transition metal;
• and
• growing the core nanocrystal into rod shape,
• wherein the grown core nanocrystal is doped with the transition metal only at one of longitudinal ends of the grown core nanocrystal, and the other one of the longitudinal ends of the grown core nanocrystal is not doped with any other chemical element,
• wherein the grown core nanocrystal is made of a chemical compound including Zn and the transition metal is a metal selected from a group consisting of Cu2+, Tb3+ and Mn2+, the transition metal has a weight % of about 0.1 to about 50 with respect to the grown core nanocrystal, and a size of the grown core nanocrystal is about 10 nm to about 10000 nm.
