我们阐明的晶体性质和三维取向的孤立的有机纳米晶体嵌入在溶胶-凝胶基质中，使用偏振非线性显微镜技术，结合双光子荧光和二次谐波产生。这种技术允许单晶结构和纳米级多晶聚集体之间的区别负责不相干的二次谐波信号。
We elucidate the crystalline nature and the three-dimensional orientation of isolated organic nanocrystals embedded in a sol-gel matrix, using a polarized nonlinear microscopy technique that combines two-photon fluorescence and second harmonic generation. This technique allows the distinction between monocrystalline structures and nanoscale polycrystalline aggregates responsible for incoherent second harmonic signals.
