Charge-transfer excitons (CTEs) immensely enrich property-tuning capabilities of semiconducting materials. However, such concept has been remaining as unexplored topic within halide perovskite structures. Here, we report that CTEs can be effectively formed in heterostructured 2D perovskites prepared by mixing PEA<sub>2</sub>PbI<sub>4</sub>:PEA<sub>2</sub>SnI<sub>4</sub>, functioning as host and guest components. Remarkably, a broad emission can be demonstrated with quick formation of 3 ps but pr ...[more]
