"This latest breakthrough along with other recent advances in quantum dot chemistry and device engineering that we have achieved suggest that laser diodes assembled from solution may soon become a reality," said Victor Klimov, head of the quantum dot group at Los Alamos National Laboratory. "Quantum dot displays and television sets are already available as commercial products. The colloidal quantum dot lasers seem to be next in line."

Colloidal quantum dot lasers can be manufactured using cheaper, simpler methods than modern semiconductor laser diodes that require sophisticated, vacuum-based, layer-by-layer deposition techniques. Solution-processable lasers can be produced in less-challenging lab and factory conditions, and could lead to devices that would benefit a number of emerging fields including integrated photonic circuits, optical circuitry, lab-on-a-chip platforms, and wearable devices.
