摘      要：This work reports the cost-effective growth of Mg:PbI2 nanostructures with 0,1,2.5 and 5.0 wt.%Mg doping ***,vibrational,morphological properties are analyzed using x-ray diffraction(XRD),Raman spectroscopy and scanning electron microscopy(SEM).XRD and Raman studies confirm the monophasic hexagonal system of Mg:PbI2,and no additional impurity peaks are *** Scherrer formula is used to determine sizes of crystallites to be in the range of 47-52 ***/SEM e-mapping analyses confirm the incorporation of Mg in PbI2 matrix and its uniform distribution throughout the *** hexagonal nanosheet-and nanoplate-like morphologies are detected in SEM images for pure and Mg-doped *** optical band gap of nanostructures is obtained from Tauc’s relation to be in the range 3.0-3.25 *** and electrical properties are found in significant enhancement as Mg doping in PbI2 matrix,also the conduction mechanism is discussed.
