Near-infrared photomultiplier detector

需要资金来更换一台已有15年历史、现已无法使用的近红外光电倍增管(NIR-PMT)，它是我的研究计划中400至1700纳米范围内所有测量的基本探测器。这现在已成为最紧迫的问题，因为近红外PMT自今年5月以来已经死亡。考虑到这种光学设备的年代久远和大量使用，这种消亡是完全正常的；多年来，它一直很好地服务于我。如果没有这个探测器，我的研究计划将严重受损。我的国际声誉建立在三价稀土离子的光学性质上，特别是那些在近红外发射的离子，包括1400到1700纳米之间的电信窗口。这项研究最初是由荷兰的一名博士生发起的，但自从我2002年来到维多利亚以来，这项研究已经真正开始了。自那以来，100多种出版物中的大多数都有通过这一近红外PMT获得的数据。三价稀土离子独特的光学和磁学性质仍然令人着迷，它们与我们的社会的相关性不断增加。它们的应用领域包括催化、照明、(生物)标记、核磁共振成像、超强磁体等等。

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.
