Formation of CsPbI3 γ‐Phase at 80 °C by Europium‐Assisted Snowplow Effect

Formation of CsPbI3 γ‐Phase at 80 °C by Europium‐Assisted Snowplow Effect

Herein, the convenient interplay between Eu incorporation and morphology to form the perovskite (PSK) γ‐phase of CsPbI3 at 80 °C (low temperature [LT] γ‐phase) is unveiled. In contrast, CsPbI3 without Eu exists in a mixture of γ‐phase and non‐PSK δ‐phase at 65 °C or in a fully δ‐phase at 80 °C. Base...
