By defining a periodic array of sub-micron sized holes into a thin film, it is possible to create an optical material in which the propagation of light can be controlled. By placing a physical defect into such a 'photonic-crystal', it is possible to create a volume within which light can be very strongly localized (trapped). Such defects are termed 'optical nano-cavities'. When a light-emitting material is placed within a nano-cavity, many fascinating physical processes can occur, including a significant enhancement of radiative-emission rates. Whilst much progress has been made on this topic by using inorganic semiconductors to define the nanocavity (or as the material located within the nano-cavity), very little has been done in this respect using organic materials. It is clear however that organic semiconductors have a number of advantages over their inorganic counterparts; these include an ease of processing and patterning at high spatial resolution and room-temperature light emission. In this proposal, we therefore intend develop two different ultra-high resolution patterning techniques that will permit us to deposit fluorescent organic materials within an optical nano-cavity. This will represent the first realisation of an optical 'organic-nanocavity' and will permit us to explore structures in which we can anticipate a significant enhancement of radiative rates. If successful, the structures that we study are likely to be of significant fundamental interest for their quantum optical properties. However we believe that organic optical nano-cavities could well find applications in a range of emerging nanotechnologies, including structures that could act as ultra-high sensitivity biological or chemical assay-systems.

通过在薄膜上定义一个亚微米大小的孔的周期性阵列，就有可能制造出一种光学材料，在这种材料中光的传播可以被控制。通过在这样的“光子晶体”中放置一个物理缺陷，就有可能创造出一个体积，在这个体积内，光可以非常强地定位（被捕获）。这种缺陷被称为“光学纳米空腔”。当发光材料被放置在纳米腔中时，会发生许多令人着迷的物理过程，包括辐射发射率的显著增强。虽然使用无机半导体来定义纳米腔（或作为纳米腔内的材料）在这一主题上取得了很大进展，但使用有机材料在这方面做得很少。然而，很明显，有机半导体比无机半导体有许多优势；这些包括易于处理和图案在高空间分辨率和室温光发射。因此，在本提案中，我们打算开发两种不同的超高分辨率图像化技术，这将允许我们在光学纳米腔内沉积荧光有机材料。这将代表光学“有机纳米空腔”的首次实现，并将允许我们探索可以预测辐射率显著增强的结构。如果成功，我们研究的结构很可能对其量子光学特性具有重要的基础意义。然而，我们相信有机光学纳米空腔可以很好地应用于一系列新兴的纳米技术，包括可以作为超高灵敏度生物或化学分析系统的结构。
