Figure 6From: Well-integrated ZnO nanorod arrays on conductive textiles by electrochemical synthesis and their physical propertiesRoom-temperature PL spectra. Bare CT substrate and the synthesized ZnO on the seed-coated CT substrate at different external cathodic voltages from −1.6 to −2.8 V for 1 h under ultrasonic agitation. The inset shows the PL peak intensity and FWHM of the synthesized ZnO as a function of external cathodic voltage.Back to article page
