用亚硒酸溶液电镀硒薄膜。从这种溶液中电析出的硒原子可牢固地粘附于表面经过细金钢砂打磨过的镍衬底上。在室温下沉积的硒膜为无定形,呈红色。但经200℃热处理可转变为平均晶粒尺寸达1.0μm的六角晶硒。
Selenium film with selenium acid solution plating. The selenium atoms electrochemically precipitated from this solution adhere strongly to the nickel substrate whose surface has been polished with fine grit. The selenium film deposited at room temperature is amorphous and red. But after 200 ℃ heat treatment can be transformed into the average grain size of 1.0μm hexagonal selenium.
