Lattice strain plays a vital role in tailoring the optoelectronic performance of colloidal nanocrystals (NCs) with exotic geometries. Although optical identifications lattice irregular-shaped NCs or hetero-structured have been well documented, less is known about signatures sparsely distributed mismatch chemically-doped NCs. Here, we show that coherent acoustic phonons (CAPs) following bandgap excitations Cu-doped CdSe quantum wells (CQWs) offer unique platform for indirectly measuring...
Doping of bulk semiconductors has revealed widespread success in optoelectronic applications. In the past few decades, substantial effort been engaged for doping at nanoscale. Recently, doped colloidal quantum dots (CQDs) have demonstrated to be promising materials luminescent solar concentrators (LSCs) as they can engineered providing highly tunable and Stokes‐shifted emission spectrum. However, existing CQDs that are aimed full spectrum LSCs suffer from moderately low efficiency,...
Abstract Colloidal quantum wells (CQWs) are regarded as a highly promising class of optoelectronic materials, thanks to their unique excitonic characteristics high extinction coefficients and ultranarrow emission bandwidths. Although the exploration CQWs in light‐emitting diodes (LEDs) is impressive, performance CQW‐LEDs lags far behind other types soft‐material LEDs (e.g., organic LEDs, colloidal‐quantum‐dot perovskite LEDs). Herein, high‐efficiency reaching close theoretical limit...
