According to Zhejiang Daily, on December 27, the list of the 2023 Damo Academy Young Scholars Award was announced, and Yang Zongyin became one of the four Zhejiang young scholars who won the award. Yang Zongyin developed the world's smallest spectrometer. He proposed a new structure that replaces the large components such as gratings, detector arrays and collimated optical paths used in traditional spectrometers with semiconductor nanomaterials, and the structure is very simple, so the size can be reduced to one-thousandth of that of traditional spectrometers. The spectrometer can be used for single-cell hyperspectral imaging, spectral monitoring, and screening. In addition, the microspectrometer can be extended from visible to mid-infrared by replacing materials, opening up more applications, such as blood glucose testing.
Before the dawn appeared, Yang Zongyin had been studying back and forth for 8 years and failed more than 150 times. Happily, his paper was submitted to the journal Science in May of the following year and accepted in July. The editors of Science commented that this achievement is "the world's most advanced material synthesis, the most superb experimental skills, and the most ingenious algorithm", and Yang Zongyin's scientific research achievements have also made China walk in the forefront of the world in the field of spectrometer miniaturization. The Science paper published at the time, the Cambridge University press release, was headlined Beyond the Limits of Newton's Optical Experiments.
- Definition and classification of spectrometers
Spectroscope is a scientific instrument that decomposes complex light into spectral lines, which is composed of prisms or diffraction gratings, etc., and can be used to measure the light reflected from the surface of objects, and can be widely used in various fields including food, chemistry, electronics, air pollution, and water pollution.
From the perspective of principle, spectroscopy instruments can be divided into: absorption spectrum (ultraviolet absorption, visible absorption, ultraviolet-visible absorption, gas-phase molecular absorption, infrared absorption, atomic absorption, etc.), emission spectrum (fluorescence, Raman, microwave plasma, etc.), optical rotation spectroscopy, etc.; From the perspective of application, it can be divided into molecular spectroscopy (infrared, ultraviolet, visible, ultraviolet-visible, optical rotation, gas phase molecule, fluorescence, Raman, etc.), atomic spectroscopy (atomic absorption, atomic fluorescence, etc.).
According to preliminary statistics, there are more than 20 kinds of spectroscopic instruments in the world. However, the most used, widespread, and representative spectroscopy instruments are ultraviolet spectroscopy, infrared spectroscopy, atomic absorption spectroscopy, etc. In addition, the development of laser Raman spectroscopy and near-infrared spectroscopy is also very popular.
-- The market scale has increased steadily
It is an important classification of scientific instruments for spectral analysis instruments, which has the advantages of complete functions, easy operation and accurate analysis, and is an ideal detection equipment in many fields. Nowadays, the spectral analysis instrument industry is developing rapidly, and the market demand is becoming increasingly prominent. According to the data analysis of the China Association for Analysis and Testing, between 2015 and 2018, the compound annual growth rate of the mainland spectroscopy instrument market reached 7%, and the market size reached 852 million US dollars in 2018, equivalent to about 5.638 billion yuan (converted according to the average exchange rate of RMB against the US dollar in 2018 announced by the National Bureau of Statistics 6.61741).
——Analysis of industry development trends
Analytical instruments belong to the high-tech field, and they have been in rapid development and change since they were applied to industry and production. With the industrial upgrading driven by technological development, the number and weight limit of the detected object will be further reduced in the future spectrometer detection, and the accuracy of detection will be further improved. At present, convenient handheld spectrometers have appeared in the mainland market, and well-known brands at home and abroad have competed in the field of portable spectrometers. At the same time, with the advent of the 5G era and the Internet of Things era of the Internet of Everything, the trend of miniaturization and intelligence of a single device in the field of spectrometers is more obvious.
According to the analysis of the Prospective Industry Research Institute, with the continuous development of spectroscopy technology and spectroscopy instruments in the direction of high-tech knowledge intensification, the application of spectroscopy instruments continues to broaden and the application in the original field is further deepened. At present, from the perspective of the development trend of spectrometers, the market of laboratory-grade large-scale spectrometers has stabilized, while the application of spectral detection in industry and life continues to expand, and small spectroscopy is a new physical dimension that is emerging. It is predicted that from 2019 to 2024, the entire spectrometer market will grow at an annual growth rate of 4%, while the compound annual growth rate of small/micro spectrometers will reach 7%, and the entire spectrometer market will reach $10.4 billion in 2024.
