Stimulated emission and lasing from CdSe/CdS/ZnS core-multi-shell quantum dots by simultaneous three-photon absorption
Three-photon pumped stimulated emission and coherent random lasing from colloidal CdSe/CdS/ZnS core-multi-shell quantum dots are achieved for the first time. Our results could offer new possibilities in biology and photonics ...
Blue liquid lasers from solution of CdZnS/ZnS ternary alloy quantum dots with quasi-continuous pumping
A blue (ca. 440 nm) liquid laser with an ultra-low threshold through which quasi-continuous wave pumping is accessible is achieved by engineering unconventional ternary CdZnS/ZnS alloyed-core/shell QDs. Such an achievement ...
