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".
La détection spectrale joue un rôle important dans l'analyse chimique, la détection des aliments, la détection biologique et d'autres domaines. Les équipements traditionnels de détection spectrale sont encombrants et coûteux. Cependant, la réduction de la taille de ses composants internes entraînera une diminution significative de ses performances. Par conséquent, la miniaturisation des équipements de détection spectrale est l'un des défis techniques majeurs auxquels est confronté le domaine scientifique et technologique.
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.
