Near-infrared photomultiplier detector

申请资金更换一个使用了15年，现在无法操作的近红外光电倍增管（NIR-PMT），这是我研究计划中400至1700纳米之间所有测量的重要探测器。由于NIR-PMT自今年5月以来已经死亡，因此现在已成为最紧迫的问题。考虑到这种光学设备的年龄和大量使用，这种消亡是完全正常的；这么多年来，这对我很有帮助。没有这个探测器，我的研究计划将受到严重影响。我的国际声誉是建立在三价镧系离子的光学特性上的，特别是那些在近红外波段发射的，其中包括1400到1700纳米之间的通信窗口。这项研究是由一名荷兰的博士生发起的，但自从我2002年到达维多利亚以来，这项研究才真正开始发展起来。此后100多份出版物中的大多数都有通过NIR-PMT获得的数据。三价镧系离子独特的光学和磁性仍然令人着迷，它们与我们社会的相关性不断增加。它们在催化、照明、（生物）标记、核磁共振成像、超强磁铁等领域都有应用。

Funds are requested to replace a 15-year old and now inoperable near-infrared photomultiplier (NIR-PMT), which is an essential detector for all the measurements between 400 and 1700 nm of my research programme. It has now become a matter of the greatest urgency because the NIR-PMT has been dead since May this year. This demise is totally normal for this optical device given its age and heavy use; it has served me well over the years. My research programme will be seriously compromised without this detector. My international reputation has been built around the optical properties of the trivalent lanthanide ions, in particular those that emit in the near-infrared, which includes the telecommunication window between 1400 and 1700 nm. This research was initiated with one PhD student in The Netherlands, but has really taken off since my arrival in Victoria in 2002. The majority of more than 100 publications since have data in them that were obtained through this NIR-PMT. The unique optical and magnetic properties of the trivalent lanthanide ions remain fascinating and their relevance for our society keeps increasing. They find applications from catalysis, to lighting, to (bio)labelling, to MRI (Magnetic Resonance Imaging), to ultrastrong magnets, to name just a few.
