Paper Abstract

We present our recent research results on luminescence of halide perovskites under various excitation sources: photoexcitation, electrical current and high-energy radiation. Our photonics crystal can reduce the emission rate of perovskite film by preventing the photoluminescence coupling to the film, but enhance the out-coupling efficiency by 23.5 times. Our solution-grown single-crystal perovskite hetero-structure was successful with different halide compositions. A pristine single-crystal light emitting device was demonstrated with excellent protection and encapsulation from material synthesis to device characterization. Lastly, with engineered perovskite materials we demonstrate a multifunctional scintillator for high-energy radiation from X-rays, gamma rays to thermal neutrons.
