We request funding to repair and upgrade an intensified, gated charge-coupled device (CCD) camera, an advanced electronic light sensor, that is dedicated to time-resolved photoluminescence spectroscopy.  In this application, light that is emitted by semiconductors is measured as a function of time after the sample is excited by a short laser pulse.  This measurement allows us to unravel the semiconductor physics of the materials under study, namely the electronic dynamics that underpin the semiconductor properties.  Our camera has suffered damage due to accidental overexposure to a calibration light source.  This damage makes routine data acquisition problematic, and it cripples what is otherwise a state-of-the-art facility for time-resolved spectroscopy for materials research (with a total investment of approximately 1.5M$).  A modest investment to repair it will allow us to maximise the research output of this facility and will contribute to our first-class training of highly-qualified personnel.We also request funding to purchase an additional CCD camera that will enhance significantly the combined experimental facility of the two investigators in this proposal.  This new camera will close the detectability gap at the interface between the visible and near-infrared parts of the light spectrum, and it will allow us to make highly sensitive optical measurements necessary for the characterisation of our materials.

我们申请资金用于维修和升级一台增强型门控电荷耦合器件（CCD）相机，这是一种先进的电子光传感器，专用于时间分辨光致发光光谱。在此应用中，在样品被短激光脉冲激发后，半导体发出的光被测量为时间的函数。这种测量使我们能够解开材料的半导体物理学，研究，即支撑半导体特性的电子动力学。我们的相机由于意外过度照射校准光源而受到损坏。这种损坏使常规数据采集成为问题，它削弱了原本是最先进的用于材料研究的时间分辨光谱学设备（总投资约150万美元）。对它进行适度的投资修复将使我们能够最大限度地提高该设施的研究产出，并将有助于我们培养一流的高水平-我们亦要求拨款购买一部额外的电荷耦合摄影机，以大大加强本建议书内两个研究机构的合并实验设施。这部新摄影机将可填补可见光与近红外之间的可探测性差距。这将使我们能够对我们的材料进行表征所需的高灵敏度光学测量。
