In the past autotype coating is very thick, there was very thin stuff now, also have autotype function
Best concentration of ions is 1. 5mol / l and dispersant pvp monomer 0. 8mol / l. spin - coating speed, which affected the quality of limn2o4 film greatly, was also studied. it demonstrated that smooth limn2o4 film without cracks could formed under 2000 rotates / min with the solution cion = 1. 5mol / l, cpvp = 0. 8mol / l, what ’ s more, fewest spin - coating times were needed at that speed
實驗結果表明:採用離子總濃度溶液為1 . 5mol / l ，聚乙烯吡咯烷酮單元濃度為0 . 8mol / l的溶液旋轉塗覆時，轉速在2000轉/分鐘時最佳，所得到的濕limn204薄膜平整光滑均勻，加熱后無龜裂現象。
This film is deposited on the surface of the glass by evaporating crystals, use of cryolite or magnesium fluoride, in a vacuum.
