“…The electrical and optical properties of ZnO nanostructures can be easily changed to controlled with controlled size, morphology and doping level. ZnO nanomaterial metal doping includes Mg (Shewale and Yu 2016), In (Nam, Kim, and Leem 2015;Tang et al 2015), Ce Li et al 2015a, Pd (Öztürk et al 2016), Eu (Chandrasekhar et al 2015;Khataee et al 2015), Co (Habibi and Shojaee 2015), Er (Bu 2015), Al (Bu 2015;Yoo et al 2015), Ni (Kaneva, Dimitrov, and Dushkin 2011), Cu (Li et al 2015a; Wang and Su 2016), Fe (Amiri et al 2016), Ag (Ansari et al 2014;Braiek et al 2015;Hsu et al 2014;Kumari et al 2015;Mosquera et al 2015;Patil et al 2016;Sahu et al 2012) and nonmetal doping includes F (Li et al 2015a), C (Ge et al 2015;Li et al 2015b), N (Bu 2015), and Cl (Chikoidze et al 2008). To produce p-type conductivity and enhance luminescence yield of ZnO doped with silver where its acts as an electron acceptor in the material (Bechambi et al 2015;Kang et al 2006).…”
