Short Time and Low Temperature Reaction between Metal Oxides through Microwave-Assisted Hydrothermal Method

Figure 4

PL emission spectra of samples prepared with different cadmium precursor (CdO) amounts and reaction time of 60 min. The inset shows the total light output, for reaction times of 20 min and 60 min, obtained from the area under the luminescence curves, as function of Cd/W atomic ratio, as determined by EDX.
