Deep‐Red Perovskite Light‐Emitting Diodes Based on One‐Step‐Formed γ‐CsPbI3 Cuboid Crystallites
An accomplished one-step approach to sitting down payment γ-phase 3D CsPbI3 movies including cuboid crystallites is attained by presenting 1,3-propanediamine dihydriodide (PDAI). The PDAI-perovskite light-emit …
