見(jiàn)笑了,字典翻譯是定向腐蝕劑,不知道對(duì)不對(duì)。 selenium powder (Se, 99.5%, Acros), sulfur (99.999%, Acros), ODE(tech., 90%, Aldrich), tri- n-octylphosphine oxide (TOPO, 99%, Aldrich), selenium (99.5+%, Acros), hexane (anhydrous, 95%, Aldrich) The lead precursor was prepared by dissolving 0.45 g (2.0 mmol) of lead oxide in a mixture of 1.6 g of OA and 4g of ODE by heating the flask to 200 °C for 30 min. Prior to the injection the temperature of the Pb solution was lowered to 140 °C。 |
