Recently, many researchers have been absorbed in synthesis of perovskites because of superior optical properties such as tunable wavelength, high photoluminescence quantum yield (PLQY) and narrow full width at half maximum (FWHM). However, there are some obstacles for practical applications; low stability of water, UV and heat, low electroluminescence properties and toxicity of lead. Green and Red emitting perovskites are improved in some degree but, blue emitting perovskites suffered from poor performance. Herein, we synthesis blue emitting CsPbBr3 with doping metal halides and supplementing organic ligands to producing stable and bright blue emitting perovskites. In addition, by fabricating light-emitting diodes with doped perovskites, we could realize that metal halides and additive ligands improved stability and electric properties. |
