“…The noticed red shift in the band gap is due to Mn doping in ZnO. A similar narrowing of band gap was also observed in other studies [41,52]. The observed decrease in energy band gap of the Mn doped ZnO is related to the shrinkage effect of the optical energy band gap.…”

“…The diminution of crystallite sizes with the increasing content of dopant is related to the increase of strain in lattice structure; however, it does not exist a direct relationship between particle size and dopant content because it depends on different factors, such as synthesis route and agglomeration. The same dependence between crystallite size and dopant content was reported in previous works for Mn‐doped ZnO and Eu‐doped TiO 2 . Huang et al.…”

“…Processes in which transitions with the photo-generated holes at the surface of the NPs are trapped by O2-ions are probably responsible for the visible emission of those NPs. Doping with Mn could increase these surface defects of NPs and improve the action of PDT.. X-Ray Diffraction (XRD) patterns of ZnO:Mn+2 NPs showed several peaks with 2Ɵ of 31.67°, 34.31°, 36.14°, 47.40°, 56.52°, 62.73°, 66.28°, 67.91° and 69.03° corresponding to (100), (002), (101), (102), (110), (103), (200), (112) and (201) planes), indicating an hexagonal wurtzite structure 23,52 . No additional peaks related to any other impurities were detected.…”
