Reveal the Humidity Effect on the Phase Pure CsPbBr₃ Single Crystals Formation at Room Temperature and Its Application for Ultrahigh Sensitive X‐Ray Detector (Adv. Sci. 2/2022)

CsPbBr3 perovskite single crystals High quality phase pure CsPbBr3 perovskite single crystals are grown by solvent evaporation method under controlled humidity conditions. Meanwhile, the humidity is revealed as a key factor affecting the phase transformation of CsPbBr3 at room temperature. Moreover, the prepared CsPbBr3 single crystals are applied for the long-term working high performance X-ray detectors.
