Lead Sulfide Quantum Dots

Lead sulfide (PbS) quantum dots are tiny particles at the nanometer scale, composed of lead and sulfur atoms. Due to their small size, they exhibit unique optical and electronic properties, particularly their ability to absorb and emit light in the infrared spectrum. These qualities make them valuable in applications like infrared imaging, solar cells, and sensors. Their quantum-scale dimensions cause their behavior to differ significantly from bulk material, enabling precise control over their properties for advanced technological uses.
