Intraband Exciton Dynamics of n-Doped Silver Selenide Quantum Dots.

ABSTRACT: Ag_xSe (x > 2) colloidal quantum dots (CQDs) have recently emerged as a promising environmentally friendly material contender for mid- and long-wave infrared optoelectronics, leveraging their intraband transition (1S_e-1P_e). However, multicarrier interactions in CQDs, particularly Auger recombination, have profound implications on the optoelectronic properties of the materials and their potential in device applications. Understanding the intraband excited-state dynamics in n-doped Ag_xSe is therefore essential for the assessment and successful implementation of this material platform in devices. We, herein, investigate the carrier dynamics of Ag_xSe in both solution and thin-film states using a femtosecond mid-i
