Abstract
PbS is an attractive semiconductor for the fabrication of quantum dots (QDs) because of its large bulk Borh exciton radius (18 nm). The features of PbS are confirmed by conducting absorption saturation measurements in different PbS-doped glasses at room temperature. With a modest energy and fast response time, large absorption change emerged. This result is encouraging for possible applications of PbS QDs as passive Q-switch or optical modulator.
