- Abstract
- Despite the excellent performance of halide perovskite, low stability, and ion exchange between halides have remained obstacles to practical application. Herein, the polymer capsule encapsulated perovskite through the conventional hot-injection method is reported to overcome the above issues. The residual heat generated during perovskite synthesis is utilized to expand the layer, and the perovskite particles are grown inside the polyethylene capsule. The products are gathered in a powder state, and the whole emission range can be synthesized. The water stability after 6 h soaked in water shows approximate to 90% and approximate to 75% for green and red, respectively. Also, due to the suppressed ion exchange, the single multi-conversion layer for white light generation can be fabricated.
