Ultrastable low-cost colloidal quantum dot microlasers of operative temperature up to 450 K

High-performance micro-/nanostructure lasers, as multifunctional optical source components, are of great importance for optoelectronic devices. Towards this goal, Scientist in China invented a high-efficiency ultrastable low-cost quantum dot microlasers, which can be operated even at 450 K, and this is the highest operational temperature for quantum dot lasers. The innovative technique substantively promotes its development stage from the basal performance study to the senior practical compatibility for high-temperature low-cost microlasers and the predictable commercialization.
