WebOct 30, 2024 · The journal of physical chemistry letters. In this work, the lasing performance of a single micro micro-sized single-crystal CsPbI3 triangular pyramid (MSCTP) is evaluated by measuring the lasing threshold at low temperature. The MSCTPs of well-defined facets are synthesized on Si/SiO2 substrate with a quartz-tube chemical vapor deposition furnace. WebSep 16, 2024 · Although inorganic perovskite, CsPbI3, shows superior thermal stability over organic–inorganic hybrid perovskites, stabilization of the photoactive black phase (α-CsPbI3) of CsPbI3 perovskite at room temperature and in ambient conditions has remained a challenge. Herein, we present a method of stabilizing the α-CsPbI3 at lower annealing … chitty chitty bang bang junior the musical
