Zn1−xGax/2Fex/2O (x= 0, 0.0156, 0.0312) represents the polycrystalline hexagonal (wurtzite) phase with a space group P63mc synthesized using the sol–gel technique. A comparative study and investigation of structural, optical, and photo-sensing properties of these samples were performed. Structural and vibrational studies show enhancement in the crystallinity of the codoped samples. Optical band gap increases from ∼3.21 to 3.24 eV with substitution because of the improved crystallinity. The photoluminescence properties show modification from yellowish green for x= 0 to a more distinct green for x= 0.0156. The intensity of the luminescence decreases with doping, indicating an overall reduction of defects in the band gap helping the material to become more transparent to visible light. Photocurrent and photosensitivity are modified with the illumination wavelength (290, 450, 540 and 640 nm) with codoping. Sensitivity toward visible lights reduced with codoping. On the other hand, it is more sensitive to ultraviolet light. It indicates the material becomes more transparent for visible light and may be used as photostable device.

Zn 1- x Ga x / 2 Fe x / 2 O（x = 0，0.0156，0.0312）代表使用溶胶-凝胶技术合成的具有空间群P 6 3 mc的多晶六方（纤锌矿）相。对这些样品的结构，光学和光敏特性进行了比较研究和调查。结构和振动研究表明，共掺杂样品的结晶度增强。由于提高了结晶度，光学带隙从〜3.21eV增加到约3.21eV。对于x =，其光致发光性质显示出从黄绿色的修饰0到x = 0.0156的更鲜明的绿色。发光强度随掺杂而降低，表明带隙中缺陷的总体减少，帮助材料对可见光变得更加透明。通过共掺杂，可通过照明波长（290、450、540和640 nm）修改光电流和光敏性。共掺杂降低了对可见光的敏感度。另一方面，它对紫外线更敏感。它表明该材料对可见光变得更加透明，可以用作光稳定设备。
