标题：mn-doped cspbcl3 perovskite quantum dots (pqds) incorporated into silica/alumina particles used for wleds

abstact：recently, more and more scholars synthesised the mn-doped cspbx3 (x = cl, br, i) inorganic perovskite quantum dots (pqds), which exhibited a strong dopant luminescence characteristic of d-d transition of mn2 and dual-color emission. however, mn-doped cspbcl3 pqds suffer from the instability, which hindered the application of pqds in optoelectronic devices. here, we resolve this problem with sio2/al2o3 monolith (sam) through a simple sol-gel process and obtained a robust luminescent pqds-sio2/al2o3 monolith (pqds-sam) with surprising high stability. this is an easy one-pot operation and can be done with large quantities. the composites not only maintain the pqds remarkable optical properties, but also improve their stability, which is significantly. the mn-doped cspbcl3 pqds-sam in powder form is easily mixed into the resins and applied as color-converting layer with curing on blue light-emitting diodes (led). and above all, the orange pqds-sam composite is used as red phosphor and stack on the ce3 : yag phosphor-in-glass (ce-pig) via screen-printing technology (ce-pig&r-pqds-sam). whereafter, warm wled is constructed by blending the ce-pig&r-pqds-sam materials with the ingan blue chips. and the constructed wleds generate a warm white with an optimal luminous efficacy (le) of 80.91 l m/w, a high cri of 83.8, and a low cct of 4082 k.
