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".
Spektraldeteksjon spiller en viktig rolle innen kjemisk analyse, matdeteksjon, biologisk deteksjon og andre felt. Tradisjonelt utstyr for spektraldeteksjon er klumpete og dyrt. Å redusere størrelsen på de interne komponentene vil imidlertid føre til en betydelig reduksjon i ytelsen. Derfor er miniatyrisering av spektraldeteksjonsutstyr en av de store tekniske utfordringene det vitenskapelige og teknologiske feltet står overfor.
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.
