该平台授权（PG）将应用我们在结构照明和混合无机/有机半导体光电器件方面的国际领先专业知识，在快速发展的光控制造领域创造新的机会。结构照明场原则上可以从无机（GaN）和有机led中获得，通过中继光学在宏观尺度上实现，或衰减到微观尺度。光聚合材料的新型制造首先涉及使用结构化照明作为控制机动阶段的新手段。该技术可与模式可编程的UV激发相结合，用于无掩膜光刻图案，在更大范围内连续光固化，局部光化学沉积或其他形式的光不稳定组装。也可以设想工艺变体，其中任意定位的荧光物体或标记物被“猎杀”，然后进行光束激发进行光固化或靶向光激发。例如，这种方法可以用来固定单个胶体量子点，作为量子技术应用中的发射器。具有传感能力的多功能设备，如用于爆炸物探测的有机激光器，是在远程条件下操作的自动化设备的另一个很好的例子。该技术的设想用途的进一步例子包括：[1]用于管理高价值物品（艺术品，核燃料容器）的LED微显示资产标签被动式资产标签包含独特的荧光物体微图案(例如：胶体量子点，有机大分子)用于更高体积，防伪应用用于精细化工生产的可定制连续流微反应器能量收集微模块为其他自主微系统提供动力，我们将重点关注有机光伏和环境辐射（RF）方法。

This Platform Grant (PG) will apply our internationally-leading expertise in structured illumination and hybrid inorganic/organic semiconductor optoelectronic devices to create new opportunities in the rapidly developing field of light-controlled manufacturing. Structured illumination fields can in principle be obtained from both inorganic (GaN) and organic LEDs, implemented on a macroscale via relay optics, or demagnified to a microscale. Novel manufacturing with photopolymerisable materials can firstly involve use of structured illumination as a novel means to control motorised stages. This technique can be combined with pattern-programmable UV excitation for mask-free photolithographic patterning, continuous photo-curing over larger fields, localised photochemical deposition, or other forms of photo-labile assembly. Process variants can also be envisaged in which arbitrarily positioned fluorescent objects or markers are 'hunted', and then subject to beam excitation for photocuring or targeted photoexcitation. This method could be used, for example, to immobilise individual colloidal quantum dots for use as emitters in quantum technology applications. Multifunctional devices with sensing ability, such as organic lasers for explosives detection, represent another excellent example of automated devices operating under remote conditions. Further examples of the envisaged uses of this technology include:[1] LED microdisplay asset tags for management of high-value objects (artworks, nuclear fuel containers).[2] Passive asset tags containing unique micro-patterns of fluorescent objects (eg. colloidal quantum dots, organic macromolecules) for higher-volume, anti-counterfeiting applications.[3] Customisable continuous-flow micro-reactors for fine chemical manufacturing.[4] Energy harvesting micro-modules to power other autonomous microsystems, where we will focus on organic PV and ambient-radiation (RF) approaches.
