Cs3Bi2Br9 quantum dots (QDs) with photoluminescence quantum yields (PLQYs) of up to 22% were prepared through the steady binding of octylammonium bromide and oleic acid. Excellent thermal stability and good luminescence properties have been achieved as intrinsic features of the inorganic halide perovskites, as well as the effective passivation of surface trap-states.
通过溴化辛基铵和油酸的稳定结合，制备了具有高达 22%的光致发光量子产率（PLQY）的 Cs3Bi2Br9 量子点（QDs）。卤化物钙钛矿固有的优异热稳定性和良好的发光性能，以及表面陷阱态的有效钝化，实现了这一目标。
