Nanoparticles Increase Intensity of Quantum Dots' Glow

By linking individual semiconductor quantum dots with gold nanoparticles, scientists at the Brookhaven National Laboratory have demonstrated the ability to enhance the intensity of light emitted by individual quantum dots by up to 20 times. The precision method for making the light-emitting particle clusters will advance scientists' ability to study and modify the optical properties of quantum dots, and could eventually lead to improved solar energy conversion devices, light-controlled electronics, and biosensors.
