Abstract

In this paper the structural, electronic and optical properties of Mn doped Pb based cubic perovskites LiPbX3(X= Cl, Br and I) were studied by wet chemical method (sol gel method). For Mn doped LiPbX3(X= Cl, Br and I) NCs, MnCl2 and PbBr2 were added in molar feed ratio 1.35 mole% and nan crystal were examine with the help of TEM and their structure were confirmed by X-ray diffraction (XRD). Additionally, the Mn2+ ions in the LiPb(Cl/Br)3 are responsible for the wide emission at 603 nm, which has been attributed to a transition between the 4T1 and 6A1 energy level of Mn2+ 3d states. This emission characteristic indicates the potential of these Mn-doped perovskites for applications in optoelectronic devices, such as light-emitting diodes (LEDs) and phosphors. This study highlights the importance of dopant incorporation in tuning the electronic and optical properties of perovskite materials, paving the way for further exploration and development in the field of nanomaterials and optoelectronics. This paper investigates the structural, electronic, and optical properties of Mn-doped Pb-based cubic perovskites LiPbX₃ (X= Cl, Br, and I) synthesized using the sol-gel method. TEM and XRD were employed to confirm the nanocrystals’ structure, while the Mn²⁺ ions in LiPb(Cl/Br)₃ were found to emit at 603 nm, due to transitions between the 4T₁ and 6A₁ energy levels of Mn²⁺ 3d states.
