LBZA is an intermediate in preparing nanocrystalline ZnO and has been reported to be thermally unstable and decompose to ZnO after heat treatment [11]. To quantitatively determine the percentage of LBZA in the composite, thermal gravimetric analysis (TGA) and differential thermal analysis (DTA) were performed and the results are shown in Fig. 1(b) Two weight losses were identified over the temperature range from room temperature to 1000 °C. The first was observed at temperatures
