Nanocomposites of CsPbBr3 perovskite quantum dots embedded in Gd2O3∶Eu3+hollow spheres for LEDs application
文献摘要：
Gd2O3∶Eu3+@CsPbBr3 quantum dots(QDs)mesoporous hollow nanocomposites with good luminescent properties and high stability were built.Among which,the hollow Gd2O3∶Eu3+spheres and CsPbBr3 QDs were prepared by urea homogeneous precipitation and hot-injection method,respectively.Finally,the Gd2O3∶Eu3+@CsPbBr3 QDs shell-core compounds were constructed through mechanical stirring.The structure,morphology,stability and luminescent properties were studied by Fourier transform infrared spectroscopy(FT-IR),differential scanning calorimetry/thermogravity(DSC/TG),X-ray diffraction(XRD),field-emission scanning electron microscopy(FE-SEM),transmission electron microscopy(TEM),pho-toluminescence excitation/photoluminescence(PLE/PL)and life decay tools.Compared to the original CsPbBr3 QDs,Gd2O3∶Eu3+@CsPbBr3 QDs display better photostability,thermal stability and current sta-bility.The resulting Gd2O3∶Eu3+@CsPbBr3 QDs composite exhibits good yellow emission.The Gd2O3∶Eu3+@CsPbBr3 QDs mixed silicone resin was directly coated on the blue LED chip,then the w-LED device with the color coordinate of(0.31,0.32)was successfully assembled.The Gd2O3∶Eu3+@CsPbBr3 QDs compounds with excellent luminescent properties and stability are expected to be widely used in lighting and display areas.
