Further more , atomic force microscopy ( afm ) results showed no noticeable difference in grain size . it ' s concluded that magnetic treatments results in oriented stacking of vopc molecules . this change in crystal structure leads to an improvement in photoconductivity behavior : a photoreceptor used pbpc as the charge generation layer had a much shorter decay time 我們分別制備了氧化鋅( zno )酞菁鉛( pbpc )和氧化錫( sno )酞菁鉛( pbpc )多層異質復合薄膜,對兩種結構的復合薄膜進行了紫外-可見吸收光譜測試( uv - vis )和x射線衍射分析( xrd ) 。
