特征标签。该超高层公寓塔楼位于伦敦不断扩大的金丝雀码头新区,将成为该码头新区的一部分。建筑塔楼有助于重塑码头新区最后一大片未被开发场地的发展特征。它是一座同时具有标志造型和人性化规模的公寓塔楼,体现了其之于新环境的愿景、全球活力社区的延伸以及生活化社区的全新开始。塔楼几何。以现有金丝雀码头新区的建筑为背景,新塔楼的圆形外观明显区别于其正交范围内的邻居。塔楼的形态外观是超高层公寓建筑的一份声明。这栋住宅塔楼也给商业空间占据主导位置的地区增添了全新维度。项目位于金丝雀码头新区的西端,其圆形的塔楼外观能从四面八方看到,包括金丝雀码头的街道、新长廊和周围的水道。塔楼建筑还同时处理了当下和未来的背景语境,没有任何一个立面会比另一个立面更高。

We find that the emission from laterally coupled quantum dots is strongly polarized along the coupled direction[110],and its polarization anisotropy can be shaped by changing the orientation of the polarized *** the nonresonant excitation is linearly polarized perpendicular to the coupled direction[110],excitons(X_(1) and X_(2))and local biexcitons(X_(1)X_(1) and X_(2)X_(2))from the two separate quantum dots(QD_(1) and QD_(2))show emission anisotropy with a small degree of polarization(10%).On the other hand,when the excitation polarization is parallel to the coupled direction [110],the polarization anisotropy of excitons,local biexcitons,and coupled biexcitons(X_(1)X_(2))is enhanced with a degree of polarization of 74%.We also observed a consistent anisotropy in the time-resolved *** decay rate of the polarized photoluminescence intensity along the coupled direction is relatively high,but the anisotropic decay rate can be modified by changing the orientation of the polarized *** energy difference is also observed between the polarized emission spectra parallel and perpendicular to the coupled direction,and it increases by up to three times by changing the excitation polarization orientation from [110] to [110].These results suggest that the dipole-dipole interaction across the two separate quantum dots is mediated and that the anisotropic wavefunctions of the excitons and biexcitons are shaped by the excitation polarization.
