Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard was proposed by the Chinese Academy of Sciences.
This standard is under the jurisdiction of the National Nanotechnology Standardization Technical Committee (SAC/TC279).
This standard was drafted by. National Nanoscience Center, Suzhou Xingshuo Nanotechnology Co., Ltd., Wuhan University, Wuhan Hanyuan Quantum Dot Technology
Development of a limited liability company, Beijing Beida Jubang Technology Co., Ltd.
The main drafters of this standard are Liu Xiaoxiao, Ge Guanglu, Zhu Dongliang, Wang Yunjun, Pang Daiwen, Zhu Xiaobo, and Li Qingsong.
introduction
Quantum dots are fluorescent nanoparticles with quantum confinement effect, also known as nanocrystals, mainly composed of II-VI or III-V elements.
Composition, size is generally 2nm ~ 10nm. Quantum dot nanocrystals have unique optical properties. the excitation spectrum has a wide wavelength range and emits
The spectral wavelength range is narrow, the fluorescence emission peak wavelength gradually shifts with the decrease of nanocrystal size, and the fluorescence peak width and nanocrystal size
The monodisperseness of inch is related.
Cadmium-containing quantum dots have good stability, high luminous efficiency, and narrow half-peak width (the relative standard deviation of the size distribution of nanocrystals is less than 5%.
The half-width of the fluorescence emission peak is usually less than 35nm), the wavelength is adjustable, the self-absorption is small, etc., in the photoelectric conversion (such as LED devices, display
Panels, field-effect transistors, etc.) and biomedical (such as cell imaging, molecular markers/fluorescent probes, etc.) have been widely studied and
use. The development of this standard will provide a standardized and uniform characterization method for fluorescence emission spectroscopy detection of quantum dots.
