The intensity and spectral content of photoluminescence (PL) is a direct measure of numerous important material properties such as chemical composition, structure, impurities, kinetic processes and SU11274
transfer (Ding et?al., 2013, Guidelli et?al., 2015 and Karunakaran et?al., 2011). To study the influence of Pd doping of ZNWs, the room temperature photoluminescence
measurements were carried out at the excitation wavelength of 350 nm. As shown in Fig. 8, a strong high intensity emission at 376 nm and several relatively weak visible emissions in the range of 600 nm were observed for the pure ZNWs. With increasing Pd doping from 0 to 0.70, the emissions intensity was decreased. It was also shown sedimentary rock
with increased Pd content the PL emission intensities were decreased. The decreased PL emission from the Pd/ZNWs membranes suggests that the re-combination of photogenerated electrons and holes is greatly prevented (Ahmad et?al., 2013, Ding et?al., 2013, Guidelli et?al., 2015 and Karunakaran et?al., 2011; Lam et?al., 2013a, Lam et?al., 2013b, Michael et?al., 2014, Visinescu et?al., 2015, Wang et?al., 2016 and Zhang and Zeng, 2012).
