| Abstract: | The effect of postgrowth thermal annealing on ZnO/ZnCr2O4 nanocomposites synthesized by hydrothermal method has been thoroughly investigated. XRD data have clearly revealed the transformation of spinel cubic phase of ZnCr2O4 to wurtzite phase ZnO and indicated the incorporation of Cr in ZnO lattice with annealing at high temperatures. Photoluminescence spectra have shown a strong dependence of emission on annealing temperatures. This work demonstrated the unique and simple route to fabricate Cr‐doped ZnO and tuning of the luminescence with annealing temperature. Thus, the work has immense potential for optoelectronic and photovoltaic applications. |
