| description | In this paper, a high-resolution full-color transparent monitor is designed and fabricated using the synthesized quantum dots for the first time. For this purpose, about 100 compounds that had the potential to emit blue, green, and red lights were selected, and simulation was performed using the discrete dipole approximation (DDA) method, in which the shell layer was selected to be SiO<sub>2</sub> or TiO<sub>2</sub> in the first step. Among the simulated compounds with SiO<sub>2</sub> or TiO<sub>2</sub> shells, Se/SiO<sub>2</sub> and BTiO<sub>3</sub>/SiO<sub>2</sub> were selected as blue light emitters with high intensity and narrow bandwidth. Accordingly, CdSe/SiO<sub>2</sub> nanoparticles were selected as green light emitters and Au/TiO<sub>2</sub> for the red light. As the surface of the nanoparticles in their optical properties is important, reactivation of the nanoparticles’ surface is required to reach the high-intensity peak and resolution. To this end, in the second step, the surface of Se and CdSe nanoparticles reacted with ethanolamine, which can make a strong bond with cadmium atoms. The band structure and optical properties were obtained by the <i>density functional theory</i> (DFT) method. The Se/Ethanolamine and CdSe/Ethanolamine were experimentally synthesized to evaluate the theoretical results, and their optical properties were measured. To fabricate a transparent monitor, Se/Ethanolamine, CdSe/SiO<sub>2</sub>, and Au/TiO<sub>2</sub> nanoparticles were dispersed in polyvinyl alcohol (PVA) solved in water and deposited on the glass by the doctor blading technique. Finally, high-resolution videos and images were displayed on the fabricated monitor. |
