The Influence of Doping Perimidine Ruthenium Complexes on Structural, Optic, and Residual Stress Properties of ZnO Thin Films

Perimidine ruthenium complexes ([Ru(L1-2)(p-cymene)Cl]Cl) were synthesized and used to produce Ru-doped ZnO thin films by the sol–gel spin-coating method. These characterized using XRD, SEM, FT-IR, UV–Vis, photoluminescence (PL) spectra. It was determined XRD analysis that all have a hexagonal wurtzite structure. The residual stress generally compressive ranged from ? 2.117 1.4 GPa as content increased 0 6%. crystal quality tended increase, reduced with increasing Ru content. In visible range, exhibited transmittance greater than 70%. Further, optical bandgap 3.20 eV for pure film of varied between 2.76 3.18 eV. This research shows new high conjugated structures are promising dopant materials film, good crystalline properties could be obtained prepared nano-optoelectronic devices.
