碩士 === 中原大學 === 物理研究所 === 106 === Perovskite materials have been used for light-emitting materials in these years. The band gaps of these materials can be tuned by changing halide elements. In this work, we demonstrate white light-emitting diodes by using bi-layer structure. The perovskite material, CH3NH3Pb(IxBr1-x)3, was used as the first layer. The emission wavelength can be controlled by tuning the ratio of iodide and bromide. The second layer is composed of many organic materials. The white emission can be obtained by combining the emission from the first layer and the second layer.
