Yang Zongyin invented the world's smallest spectrometer and the widest wavelength tunable nanolaser through a series of pioneering researches on full-spectrum luminescence and detection. He has broken through the core technical bottleneck of the miniaturization of spectral detection equipment from the aspects of miniature spectrometer, wavelength tunable light source and synthesis of new luminescent materials, and has successfully carried out industrialization research and was selected as "Innovative 35 People".
Spektrituvastus mängib olulist rolli keemilises analüüsis, toidu tuvastamises, bioloogilises tuvastamises ja muudes valdkondades. Traditsioonilised spektraaltuvastusseadmed on mahukad ja kallid. Selle sisemiste komponentide suuruse vähendamine toob aga kaasa selle jõudluse olulise vähenemise. Seetõttu on spektraaltuvastusseadmete miniaturiseerimine üks peamisi tehnilisi väljakutseid, millega teadus- ja tehnoloogiavaldkond silmitsi seisab.
In order to meet these challenges, Zongyin Yang, a researcher at Zhejiang University, pioneered a series of theories, methods and processes for full-spectrum luminescence and detection based on graded bandgap semiconductor materials, and invented the world's smallest spectrometer.
The spectrometer replaces the gratings, detector arrays and collimated optical paths used in traditional spectrometers with semiconductor nanomaterials, and adopts the world's first miniaturized technical solution for spectrometers that integrates spectroscopic and detection. The core device is only tens of microns in size, smaller than the diameter of a human hair, and has both high performance and low cost, paving the way for the application of nanomaterials in miniature spectrometers.
In addition, Yang Zongyin also pioneered the use of graded semiconductor materials as variable gain materials for lasers, and invented the world's widest wavelength tunable nanolaser.
