发光

Characteristics of cultured pearls and treated pearls are studied by cathode luminescence microscope.

通过阴极发光仪对养殖珍珠和处理养殖珍珠的阴极发光特征进行了研究，结果表明：在阴极射线激发下，淡水养殖和处理珍珠发黄绿或绿色光，而各色海水养殖和处理珍珠不发光；阴极显微观察可见部分处理珍珠层的表面微破损。

In cathode luminescence microscope, freshwater cultured pearls and treated cultured pearls show yellow-green or green because of Mn, while other seawater cultured pearls present none fluorescence due to Sr.

淡水珍珠和海水珍珠不同的发光特点与其所含的微量过渡元素有关：淡水珍珠因富Mn而发光，海水珍珠则由于贫Mn富Sr而不发光。

Further picosecond PL studies on dendronized PFs show that the fluorene-based emission in dilute solution follows a single exponential decay, whereas those in thin film decayed in a multi-phase manner and the lifetime prolongs with the generation of dendronization. These observations are discussed in terms of dispersive transport happening between adjacent chains in film. The dispersive relaxation can be controlled by site isolation of bulky dendrons. Our results prove that dendronization is highly effective in controlling the inter-chain interactions of fluorene-based polymers.

不同代数树枝化聚芴的时间分辨荧光动力学研究结果表明，溶液状态下的发光为单指数衰减行为，而薄膜状态下的发光为多指数衰减行为，且其发光寿命随树枝化代数增加而增长，表明树枝化基团抑制了邻近的聚芴分子之间能量传递所致的激发态能量耗散。
