Plasma technology has become a major driver of the modern economy. Industrial applications are numerous and increasing due to the uniqueproperties plasmas can offer. Applications range from semiconductor manufacturing, plasma-assisted combustion to plasma medicine, plasma catalysis toplasma fusion. Plasmas are often used industrially for surface treatment or as a chemical process catalysis. Plasma glow is an inherent energy loss channel whichresults in the emission of radiation. This glow provides a helpful tool to understand what species dominate in the plasma as well as applications such as sterilisation of germs. Sometimes radiation has a negative impact on plasma processes such as radiation damage to semiconductors during microchip manufacturing. Currently, most plasma models ignore the role of radiation meaning there is a lack of knowledge about an essential process in the plasma. Without assessing the radiative processes the plasma cannot be fully understood.The proposal aims to provide the capability to model radiative processes in (technological) plasmas by combining two databases: the ExoMol database of molecularradiative properties, developed at UCL for the study of the atmospheres of exoplanets and other hot bodies, and QDB (the Quantemol DataBase) of plasma reactionsdeveloped by project partner Quantemol Ltd to provide input to models of (technological) plasmas. The combined database will be augmented by software whichwill allow full radiative-collisional modelling of the given plasma and simulated high resolution emission spectra of the resulting plasma.The project aims to provide a commercial product by the end of the grant period.

等离子体技术已经成为现代经济的主要驱动力。由于等离子体可以提供的独特特性，工业应用越来越多。应用范围从半导体制造、等离子体辅助燃烧到等离子体医学、等离子体催化到等离子体聚变。等离子体在工业上常用于表面处理或作为化学过程的催化剂。等离子体辉光是一种固有的能量损失通道，导致辐射的发射。这种发光提供了一种有用的工具，可以了解等离子体中占主导地位的物种，以及细菌灭菌等应用。有时辐射对等离子体过程有负面影响，如微芯片制造过程中对半导体的辐射损伤。目前，大多数等离子体模型忽略了辐射的作用，这意味着对等离子体中的基本过程缺乏了解。不评估等离子体的辐射过程，就不能完全了解等离子体。该提案旨在通过结合两个数据库来提供（技术）等离子体辐射过程模型的能力：由伦敦大学学院开发的ExoMol分子辐射特性数据库，用于研究系外行星和其他热体的大气，以及由项目合作伙伴Quantemol有限公司开发的QDB （Quantemol数据库）等离子体反应，为（技术）等离子体模型提供输入。合并后的数据库将通过软件进行扩充，该软件将允许对给定等离子体进行完整的辐射碰撞建模，并模拟产生的等离子体的高分辨率发射光谱。该项目的目标是在资助期结束时提供一个商业产品。
