In this investigation, we report the results of the prepared Fe3+ doped ZnCdO nanopowder by simple solution method. Several experimental techniques have been performed on the prepared samples to find out the structural, morphological and luminescence properties. X-ray diffraction has revealed that the prepared ZnCdO nanopowder possesses the hexagonal ZnO and cubic-period of CdO phase. SEM image has revealed that the tiny agglomeration of irregular particles have appeared in the prepared samples and also found that the crystallite size of the powder sample is 28 nm. FTIR peaks have revealed that the positions of the ZnO and CdO are at 836 and 860 cm−1. EPR and optical retention examination findings have been undertaken to know the site symmetry of Fe3+ ion. Photoluminescence studies have showed that the prepared material radiates yellowish green light with the CIE coordinates, x = 0.3301 and y = 0.4042. These results have revealed that the prepared nanopowder can find positional application in the preparation of optoelectronic and photoluminescence devices.
