“…Conventional core/shell QDs possess a high PL QY (e.g., > 90%) but they are small and have very high specific surface area and surface energy (tension). So the core/shell CdSe/ZnS QDs are generally chemically instable and have more non-radiative recombination processes such as Auger recombination due to thin passivation shell (12 nm) [21]. In contrast, giant QDs have much thicker ZnS shell (> 10 nm), which improves the material stability and suppresses the blinking and Auger recombination so they were considered in EL devices [22].…”

Quantum dots (QDs) are promising materials and have been considered for self‐emitting electroluminescent QD light‐emitting‐diodes (QLEDs). In this work, we report a transparent QLED fabricated with middle‐sized QDs, which has a emission peak with the wavelength of 520 nm and the full‐width at half maximum (FWHM) of 17 nm, and the photoluminescence quantum yield of ~ 90%. The electroluminescent QLED device, fabricated in atmosphere, exhibits brightness of 125, 400 cd/m2, current efficiency of 34.23 cd/A, external quantum efficiency of 8.7 %, and transmittance of 70%.

In this study, the effects of temperature and hydro-static pressure on the electronic and optical properties of the spherical core/shell/shell quantum dot structure is determined numerically. The energy eigenvalues of the system and their corresponding eigenfunctions are calculated using the diagonalization method within the framework of the effective mass approach. Then, linear, nonlinear and total intersubbands absorption coefficients and relative refractive index changes are calculated theoretically by iterative method within the framework of compact density matrix approach. With the results to be obtained from the study, it is predicted that this system can be recommended as a building block for various applications in the THz electromagnetic spectrum region.
