👉 ChemLight particles, often referred to as quantum dots or colloidal quantum dots, are nanoscale semiconductor particles that exhibit unique optical properties due to their size and structure. These particles can absorb light across a broad spectrum and re-emit it at a longer wavelength, a phenomenon known as photoluminescence. The energy levels of these particles are quantized, meaning their electronic states are discrete rather than continuous, which results in highly tunable emission colors depending on the particle's size. Smaller particles emit light at shorter wavelengths (bluer colors), while larger particles emit at longer wavelengths (redder colors). This property makes ChemLight particles valuable in various applications, including displays, biological imaging, and solar cells, where precise control over light emission is crucial.
