An all‐solution processed and all‐colloidal laser is demonstrated using tailored CdSe/CdS core/shell quantum dots, which exhibit highly stable and low‐threshold optical gain owing to substantially suppressed non‐radiative Auger recombination.
An all‐colloidal vertical‐cavity surface‐emitting laser (VCSEL) is reported by C. Dang, H. Sun, H. V. Demir and co‐workers on page 2741, which offers high performance and stability while being fully solution processed. This all‐colloidal laser is based on a stacked architecture of dielectric mirrors, based on metal oxide nanoparticles sandwiching semiconductor nanocrystals as the optical gain medium,...
