Blue-and red-shifting amplified spontaneous emission of CdSe/CdS core/shell colloidal quantum dots
(IEEE, 2013)We report blue- and red-shifting amplified spontaneous emission of CdSe/CdS quantum dots, controlled by varying core/shell dimensions and modifying exciton-exciton interactions, with low optical gain threshold of two-photon ... -
Ultralow-threshold up-converted lasing in oligofluorenes with tailored strong nonlinear absorption
(Royal Society of Chemistry, 2015)Nonlinear optical response in organic semiconductors has been an attractive property for many practical applications. For frequency up-converted lasers, to date, conjugated polymers, fluorescent dyes and small organic ...
