SUMMARY

CdS (Cadmium Sulfide) and CdSe (Cadmium Selenide) are widely used as quantum dots due to their low production costs and availability as byproducts of iron fillings. These materials have been historically undervalued, treated as waste, which contributes to their economic advantage in manufacturing. Their unique optical properties make them suitable for various applications in electronics and photonics, solidifying their position in the quantum dot market.

PREREQUISITES
  • Understanding of quantum dot technology
  • Knowledge of semiconductor materials
  • Familiarity with optical properties of materials
  • Basic concepts of material sourcing and cost analysis
NEXT STEPS
