2020年12月1日 · Here we demonstrate high performance vertical stacked 2D MoS2/CuPc heterojunction based photodetectors with high sensitivity, high external quantum efficiency and ultrafast response time.

本文构建了酞菁铜/二硫化钼(CuPc/MoS 2 )范德瓦耳斯异质结, 并对其荧光特性进行了表征和分析. 与单层MoS 2 相比较发现, 引入有机半导体CuPc后, 异质结当中发生了明显的荧光淬灭现象.

2024年7月1日 · Herein, a CuPc/DR-MoS 2 heterojunction involving copper phthalocyanine (CuPc) and molybdenum disulfide with S-rich vacancies (13.66%) is successfully prepared by the facile hydrothermal method.

Besides, the CuPc 2 thin films showed spectral PL emission in the visible region with white CIEcoordinatesm which suggests it for white light LEDs applications. The prepared CuPc 2 films integrated with the p-type silicon in an organic/inorganic heterojunction structure were evaluated electrically and the conduction mechanism was interpreted in ...

2023年2月19日 · The significant photoluminescence (PL) quenching signals indicate obvious charge transfer at the interface of the formed 2D MoS 2 /BTP-4F heterojunction. The Kelvin probe force microscope (KPFM) demonstrates the effective electron charge transfer from monolayer MoS 2 to BTP-4F film.

Here, we characterize the photoexcited dynamics of the small molecule semiconductor copper pthalocyanine (CuPc) in solution and in thin film, the latter comprising two different π-stacked...

2010年3月12日 · Cu (II) (phthalocyanine) (CuPc) is broadly utilized as an archetypal molecular semiconductor and is the most widely used blue printing pigment. CuPc crystallizes in six different forms; the chemical and physical properties are substantially modulated by its molecular packing among these polymorphs.

2016年7月28日 · The crystal structure of the β phase of copper phthalocyanine (CuPc) is a monoclinic herringbone, which is commonly created in thin films by either thermal annealing of α-CuPc at ∼300 °C or deposition on heated substrates. Of the several known CuPc crystal polymorphs, the β phase is of particular interest due to its thermodynamic stability.

2008年9月30日 · This article reports structure and morphology of copper phthalocyanine (CuPc) and fluorinated copper phthalocyanine (F 16 CuPc) pn heterojunction. Highly ordered CuPc and F 16 CuPc polycrystalline thin films with the 2 0 0 plane spacing s of 1.30 and 1.56 nm, respectively

Copper phthalocyanine (CuPc) thin films grown on glass substrates by the vacuum deposition method were investigated using photo absorption–transmission as well as photoreflectance spectroscopy with respect to different thickness. The surface morphology was investigated using scanning electron microscopy (SEM).
