Abstract:
1. A nano particle comprising: a compound semiconductor including a cadmium (Cd) and a zinc (Zn), wherein the nano particle has a diameter of about 2 nm to about 8 nm and converts a light having a wavelength of about 300 nm to about 400 nm into a light having a wavelength of about 500 nm to about 600 nm, wherein the content of the cadmium is gradually reduced from a center of the nano particle to an outer portion of the nano particle, wherein the content of the zinc is gradually increased from the center of the nano particle to the outer portion of the nano particle, and wherein the composition of the cadmium is reduced from the center of the nano particle to the outer portion of the nano particle such that at least two inflection points can be formed.
