A paper by authors from Los Alamos and Argonne national laboratories sums up the recent progress in colloidal-quantum-dot research and highlights the remaining challenges and opportunities in the rapidly developing field, which is poised to enable a wide array of new laser-based and LED-based technology applications.
"These tiny specs of semiconductor matter can generate spectrally tunable lasing light, opening tremendous opportunities in areas of photonic circuits, optical communications, lab-on-a-chip sensing, and medical diagnostics," says Victor Klimov, leader of the team at Los Alamos National Laboratory that has pioneered a range of discoveries with colloidal quantum dots.
Klimov is lead author of "Colloidal Quantum Dot Lasers," published in Nature Reviews Materials.
A distinctive feature of colloidal quantum dots is that the color of their emission depends on particle size. Highly efficient, spectrally tunable emission from colloidal nanocrystals has already been exploited in commercial products such as televisions and displays. Colloidal nanomaterials are also attractive for applications in lasing technologies as they can enable a completely new class of color-selectable lasing devices that can be processed from a solution.
