Understanding Quantum Dots
⚛️Quantum dots are nanocrystals with unique light absorption and emission properties.
🔬They have potential applications in high-end displays, solar panels, camera sensors, and more.
🏆Scientists recently won the Nobel Prize in Chemistry for their discovery of Quantum dots.
The Science Behind Quantum Dots
🌈Crystals at quantum dot scale exhibit Quantum effects, leading to color changes when excited by light.
🔍Quantum dots are a few nanometers in diameter, unimaginably tiny compared to regular crystals.
💡When light hits a quantum dot, it excites an electron to a higher energy level, resulting in color emission.
Synthesizing Quantum Dots
🧪Reaction medium helps materials dissolve for easy reaction.
🔒Argan gas pushes out air and moisture from the flask to prevent interference.
🔥Heating the flask to 300°C and adding selenium and sulfur triggers rapid formation of nanocrystals.
Properties and Applications of Quantum Dots
🌞Quantum dots absorb a wide spectrum of light, with stronger absorption for bluer light.
🎨Quantum dots emit a narrow range of light around 605 nanometers, appearing orange to red.
