Burak Guzeltruk from the Bilkent University in Turkey was awarded for his outstanding photonics research work on all colloidal lasers of solution-processed semiconductor quantum dots and quantum wells. In his PhD work, all-solution-processed lasers of colloidal semiconductor nanocrystals are developed offering single-material, full-color and highly-efficient laser technology promising for a broad range of applications including displays, spectroscopy and biomedicine. In his work, ultra-low optical gain thresholds and record-high optical gain coefficients are demonstrated in the colloidal nanocrystals through tailoring of the architecture and dimensionality in these materials. His achievements highlight that the colloidal semiconductor nanocrystals are bright materials as next-generation optical gain media.
