Title: Innovations of Chin-Cheng Chiang in Quantum Dot Technology.
Introduction
Chin-Cheng Chiang is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of quantum dot technology, holding a total of 2 patents. His work focuses on the formation and application of gigantic quantum dots, which have potential uses in various advanced technologies.
Latest Patents
Chiang's latest patents include a method of forming gigantic quantum dots. This innovative method involves several steps, starting with the creation of a first precursor by mixing zinc acetate (Zn(ac)), cadmium oxide (CdO), a surfactant, and a solvent, followed by a first heat treatment. The first precursor contains Zn-complex and Cd-complex, both having the surfactant. A second precursor, which includes elements S and Se along with trioctylphosphine (TOP), is then added to the first precursor to create a reaction mixture. After performing a second heat treatment on this mixture, it is cooled to yield the gigantic quantum dots.
The gigantic quantum dots themselves consist of a core made of CdSe, surrounded by a shell of ZnS, with an alloy positioned between the core and the shell. The composition of the alloy gradually changes, with the content of Cd and Se decreasing from the core to the shell, while the content of Zn and S increases. Each gigantic quantum dot has a particle size of 10 nm or more, showcasing the advancements in material science that Chiang has contributed to.
