As K. Wang and co‐workers describe on page 922, bright Cd‐free CuInS 2 /ZnS quantum dots (QDs) are synthesized and embedded into mesoporous silica via a swelling and evaporation method to obtain luminescent microbeans (LMBs). This prevents the deterioration and aggregation of QDs effectively. An LMB‐based white‐light‐emitting diode (WLED) achieves the highest luminous efficiency record with extreme stability. This new LMB possesses great potential to be widely applied in displays and lighting.
