The results indicated that CHCl3 was optimum reagent and the reaction temperature was better controlled at 10~15℃. Dinitrogen tetraoxide and nitric acidhad a detrimental effect on the yield and purity of 1,2-propanediol dinitrate. When the concentrations of dinitrogen tetroxide and nitric acid were below 1.00% and 5.53% respectively, these detrimental effects could be neglected. Under the optimum conditions, the yields and the purity of 1,2-propanediol dinitrate were 99.01% and 95.89%, respectively.

同时考察了反应溶剂、反应温度、N_2O_5中N_2O_4和HNO_3杂质对1，2-丙二醇二硝酸酯收率和纯度的影响，结果表明，适宜的溶剂是CHCl3；适宜的反应温度为10～15℃；在适宜条件下，1，2-丙二醇二硝酸酯的收率和纯度可分别达到99.01%和95.89%；N_2O_4和HNO_3对产物的收率和纯度均有不利影响，但当N_2O_5中N_2O_4含量小于1.00%，HNO_3含量小于5.53%时，对产物收率和纯度的影响不大。

XRD results indicate that the major diffraction peaks of the film match those of Sb2Te3. The film growth is apparently at the ［101］/［012］ orientation and many Te peaks are observed. Hall measurement reveals that all the samples are p-type and the resistivities are low. The electric conductivity of the films approaches that of the bulk metal and the carrier concentration is of 1023 cm-3. Seebeck coefficient measurement shows that the samples have nice thermoelectrical properties and the seebeck coefficients are in the range of 7.8—62 μV/K. Among all, the samples annealed at 200 ℃ for 6 h have the highest seebeck coefficient of about 62 μV/K and the lowest resistivity.

XRD测量结果显示，薄膜的主要衍射峰与Sb2Te3标准衍射峰相同，在［101］/［012］晶向取向明显，存在较多的Te杂质峰；霍尔系数测试结果表明，薄膜为p型半导体薄膜，薄膜电阻率较低，其电导率接近于金属电导率，载流子浓度量级为1023 cm-3，具有良好的电学性能；Seebeck系数测量结果显示，薄膜具有良好的热电性能，在不同条件下制备的薄膜的Seebeck系数在7.8—62 μV/K范围；在所制备的薄膜中，退火时间为6 h、退火温度为200 ℃的薄膜其Seebeck系数达到最大，约为62 μV/K，且电阻率最小。
