Cd1-xMnxTe quantum dots (QDs) were synthesised through a one-step approach in an aqueous medium, and a red-shift in the emission peak wavelength, from 542 nm to a long wavelength of 566 nm, was observed by doping Mn2+ ions into the CdTe QDs. A red light-emitting diode (LED) device was fabricated by combining red light-emitting Cd1-xMnxTe QDs with a near-UV InGaN LED chip. CIE colour coordinates of the LED at (0.56, 0.25) demonstrated a near red light-emitting LED. The results showed that the Cd1-xMnxTe QDs are good candidates for LED applications.
