铅卤钙钛矿材料由于其优异的光致和电致发光性能，如大的吸收系数、高的载流子迁移率和发光量子产率等，在太阳能电池、发光二极管等领域具有重要的应用前景。然而，铅的毒性及较差的物化及光稳定性限制了其实际应用。为了降低毒性及改善发光性能，无铅金属卤化物得到了广泛的研究，但他们通常在紫外区域有强的吸收，很难被商用蓝光芯片激发，从而限制了其在WLEDs的发光效率与应用。因此我们基于广西的丰富锰资源， 开展锰基钙...

High-power white LEDs face the same problem that Michigan Stadium faces on game day — too many people in too small of a space. Of course, there are no people inside of an LED. But there are many elect...
