Summary: Insightful knowledge on quantum nanostructured materials is crucial for engineering and utilizing their wide range of applications. Using a formalism based on the single-band effective mass equation, this study determined the light absorption of colloidal quantum dots embedded in wider bandgap semiconductors, finding that the size of the CQDs has the biggest impact on the number and energy of confined levels while the potential barrier causes a linear shift in their values. Additionally, the research showed that the absorption coefficients enabled by quantum effects can reach levels comparable to bulk semiconductors.
