In an exciting leap toward greener electronics , researchers at the University of Utah have found a way to turn food waste into quantum dots —the tiny crystals that power energy-efficient LED lights in TVs, bulbs, and screens. This breakthrough could pave the way for non-toxic, eco-friendly LEDs , replacing traditional materials like cadmium selenide , which can be harmful to the environment. What Are Quantum Dots? Quantum dots are nanoscale semiconductor particles that emit vibrant, precise colors when exposed to light or electricity. They’re used in: LED TVs & displays (for richer colors and better efficiency) Energy-saving light bulbs Medical imaging & solar cells Traditionally, these dots are made from toxic metals like cadmium , which pose environmental risks when disposed of. But now, scientists are turning to an unlikely alternative: food waste . From Bread Crusts to High-Tech Lights The Utah...
