我们报告了基于分子的一维微腔的实现，该微腔在室温下在近紫外范围内发射。活性材料是二维钙钛矿 (C6H5C2H4-NH3)(2)PbCl4 薄膜，这是一种吸收和发射约 3.6 eV 光的分子化合物。角度分辨反射率和光致发光测量表明该微腔在强耦合状态下工作。发射的紫外偏振子是钙钛矿型半导体的光子腔模式和激子之间的混合状态。 (C) 2008 年美国物理研究所。
We report on the realization of a molecule-based one-dimensional microcavity emitting in the near UV range at room temperature. The active material is a thin film of the two-dimensional perovskite (C6H5C2H4-NH3)(2)PbCl4, a molecular compound absorbing and emitting light around 3.6 eV. Angle-resolved reflectivity and photoluminescence measurements show that this microcavity works in the strong coupling regime. The emitting UV polariton is a mixed state between the photon cavity mode and the exciton of the perovskite-type semiconductor. (C) 2008 American Institute of Physics.
