Abilities of the “old” FLS 980. How to use the cryostat for measurements of the low-temperature excitation and emission spectra
dr Michał Chaika
INTiBS PAN
I am pleased to announce that our FLS 980 spectrofluorometer has recently been upgraded with a cryostat, significantly enhancing its capabilities for low-temperature measurements. With this addition, we can now extend our research into the excitation and luminescence spectra across a broad temperature range of 5K to 280K. This upgrade opens up exciting possibilities for investigating temperature-dependent phenomena in materials, such as shifts in emission wavelengths, changes in intensity, and even thermally activated processes.
The primary goal of today’s meeting is to introduce you to the full range of capabilities of the newly modified FLS 980 system and to demonstrate how it can be effectively used for both excitation and emission spectra measurements at various low temperatures. We will focus on practical aspects of using the cryostat with the FLS 980, covering everything from system setup to best practices for acquiring high-quality data.
Today's session will be more technical in nature than scientific, as we aim to provide you with the necessary knowledge for navigating the system. We will guide you through the setup process, familiarizing you with the key components of the cryostat and the spectrofluorometer, including the sample handling, temperature control, and optical alignment procedures. Additionally, we will address potential artifacts that may arise during low-temperature measurements—such as thermal gradients, condensation effects, or signal noise—and share strategies for minimizing or compensating for these issues.
By the end of this meeting, we hope to provide you with the tools and understanding necessary to make full use of this enhanced system in your research. We encourage an interactive discussion and welcome any specific questions you may have about experimental protocols, potential challenges, or technical concerns related to the system’s performance.
We look forward to seeing you at the meeting and exploring the full potential of this exciting new addition to our laboratory!
