Red Light-Emitting Diode Based on Blue InGaN Chip with CdTexS(1 - x)Quantum Dots.
Thioglycolic acid-capped CdTexS(1 - x)quantum dots (QDs) were synthesized through a one-step approach in an aqueous medium. The CdTexS(1 - x)QDs played the role of a color conversion center. The structural and luminescent properties of the obtained CdTexS(1 - x)QDs were investigated. The fabricated red light-emitting hybrid device with the CdTexS(1 - x)QDs as the phosphor and a blue InGaN chip as the excitation source showed a good luminance. The Commission Internationale de L'Eclairage coordinates of the light-emitting diode (LED) at (0.66, 0.29) demonstrated a red LED. Results showed that CdTexS(1 - x)QDs can be excited by blue or near-UV regions. This feature presents CdTexS(1 - x)QDs with an advantage over wavelength converters for LEDs.
