Abstract: (2171 Views)
In this paper synthesis of Ruddlesden-Popper tow dimensional Perovskite (RPPs) is reported. Not only has this kind of Perovskite (PVK) its 3D counterpart advantageous such as high absorption coefficient and good carrier transport properties but also its stability has been improved. In this work BA molecule which is stable, heat and humid resistive and big enough to cover a mono layer of lead tetra iodide was used to prevent heat and humidity to reach PVK layer and stabilize it. The existence of spacer molecule increase lattice constant and quantum confinement enlarge band gap. After Dip-coating photoluminescence (PL) and photo absorption spectroscopy test was done and band gap was measured 2.5eV and PL pick was 2.21eV.
