Colloidal Quantum Dots in the Photosensitive Layer Based on Perovskite
2023 Seminar on Fields, Waves, Photonics and Electro-optics: Theory and Practical Applications (FWPE)(2023)
摘要
The effect of colloidal quantum dots on the optical characteristics of photosensitive layers of the perovskite crystal structure has been investigated. The study used a comparative analysis of photosensitive layers with and without quantum dots. As a result, absorption, transmission and photoluminescence spectra were obtained. It can be concluded that the inclusion of CQD in the composition of perovskite leads to an increase of absorption and a decrease of transmission in the short-wavelength region from the peak of photoluminescence of quantum dots. It can also contribute to the shift of perovskite photoluminescence peak to the long-wavelength region.
