This project will produce devices that are capable of operating at two thirds of the temperature of the sun's surface. Micro hot plate devices will be fabricated from the Ultra High Temperature Ceramic (UHTC) Hafnium Carbide, which has a melting point above 4000 K. To put this in perspective, only three elements have higher melting points than 3300 K (W, Re and Ta). Operating these hot plates at such high temperatures will produce intense blackbody emission centred in the Near-IR with more than 1000 times the intensity of the state of the art. Such radiation is used in many industrial, medical and defence applications such as gas sensing and spectroscopy. In particular there is a new demand in mobile sensing that requires miniaturised IR light sources with broader wavelength capabilities. The proposed micro emitters are much brighter, broader wavelength and faster than what exists today and can improve the speed, precision and range of applications of existing sensing platforms.

该项目将生产能够在太阳表面温度的三分之二工作的设备。微型热板设备将从超高温度陶瓷（UHTC）碳化物制造，碳化物的熔点高于4000K。为了将其透视，只有三个元素具有比3300 K高的熔点（W，RE和TA）更高（W，RE和TA）。在这样的高温下操作这些热板将产生以近红外为中心的强烈黑体发射，其最高速度是最新情况的1000多倍。这种辐射用于许多工业，医疗和防御应用，例如气体传感和光谱法。特别是在移动传感中有新的需求，需要具有更广泛波长功能的微型红外光源。所提出的微型发射器比当今存在的微观发射器要明亮，更广泛，更广泛，并且可以提高现有传感平台的应用速度，精度和范围。
