Introductions and Applications of Quantum Dots
Abstract : Quantum dots are semiconductor nanocrystalline materials with quantum confinement effects in three dimensions of space, also known as "artificial atoms." The particle size of the quantum dot material is generally between 1-10 nm. Since the electrons and holes are quantum confined, the continuous band structure changes to a vertical energy level structure, thereby bringing a narrow luminescence spectrum (20-30 nm) , as well as h igh purity, wide color gamut and other advantages. The origin of quantum dot technology dates back to the mid-1970s. It was originally developed to solve the global energy crisis. In today's nano research field, quantum dot counting is one of the star materials. Compared with organic fluorescent materials, quantum dots have controllable emission wavelengths and research; high luminous efficiency, one-step excitation, multiple colors, strong fluorescence intensity, long-lasting anti-photobleaching, etc., which is an ideal substitute fo...
