我们描述了一种新的技术，有机气相沉积，用于光学非线性有机盐薄膜的生长。由独立控制的载气气流将盐的每一组分的挥发性前体作为蒸汽输送到热壁反应室。这些成分发生反应，在玻璃和黄金的衬底上形成一层多晶薄膜。过量的反应物和反应产物被载气从系统中清除。作为一个例子，我们展示了纯度为95%的4‘-二甲氨基-N-甲基-4-二苯乙烯(DAST)多晶光学非线性薄膜的生长。
We describe a novel technique, organic vapor phase deposition, for the growth of thin films of optically non-linear organic salts. A volatile precursor of each component of the salt is carried as a vapor to a hot-wall reaction chamber by independently controlled streams of carrier gas. The components react to form a polycrystalline thin film on substrates of glass and gold. Excess reactants and reaction products are purged from the system by the carrier gas. As an example, we demonstrate the growth of polycrystalline, optically non-linear thin films of 4'-dimethylamino-N-methyl-4-stilbazolium tosylate (DAST) with > 95% purity.
