The Study of Perovskite Quantum Dots Diffuser Film

Project Details


Perovskite quantum dots (PeQDs) with the advantages of inexpensive process and tunable wavelength over the completely visible spectral range, have received increasing attention in recent years. Given these advantages, the scientific community has extensively discussed the possibility of applications in the fields of solar cells, photoluminescence and electroluminescence. In this work, we propose the use of material surface modification and self-assembly techniques to fabricate the new perovskite quantum dots diffuser Film (PeDF). This new PeDF with the advantages of high efficiency and high purity of luminescent color, are very likely to be used in the field of micro LEDs and QLED TV in the future.We aim to develop two thematic studies in this project:(1)In terms of avoiding excessive agglomeration of the SiO2 spheres, APTES and MOTMS is using as ligand to synthesize and avoid agglomeration of PeQDs @ SiO2 spheres.(2)To improve the light uniformity and efficiency of PeDF. We proposed to fabricate SiO2 spheres with a mulberry-like shape via the self-assembly technology. Such mulberry-shaped SiO2 spheres are aggregated from sub-um-sized spheres to um-sized spheres, so they have the advantages of high specific surface area and high Mie scattering, which might enhance the efficiency and uniformity of PeDF.TFT-LCD displays and LEDs are two of the very important industries in Taiwan. In order to respond to the threats of new products and new applications in this field from Japan, South Korea and China, study and development of new products with high performance are very important topics for us. The results of this study might be applied to Micro LEDs and TFT-LCD displays and other fields, to increase the competitiveness of Taiwan.
