There’s little doubt that LEDs save energy, but the high initial cost of LED lamps is preventing mass adoption by lighting consumers. New materials are crucial to driving down the price tag and driving up market acceptance. The price of LEDs has come down rapidly over the past three years, and this trend is expected to continue over the next couple of years until LED lamps reach mass adoption cost. Essential research into better materials is crucial for reaching this price goal – but beyond that, advances in materials will also broaden LED consumption into new markets and...Read full article

    quantum dots
    A quantum dot is a nanoscale semiconductor structure, typically composed of materials like cadmium selenide or indium arsenide, that exhibits unique quantum mechanical properties. These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light) with precise wavelengths,...
