We are pleased to introduce the new Cryosphere for the FLS1000 spectrometer; the only commercial accessory for measuring photoluminescence quantum yield from 77 K to 500 K.

The Cryosphere features a software-controlled cryostat inside an integrating sphere and allows measurements of solids and powders. The absolute quantum yield as a function of temperature is easily obtained using the Fluoracle software.

In our new application note, we demonstrate the capability of the Cryosphere with the temperature-dependent quantum yield measurements of plant leaves. An FLS1000 Photoluminescence Spectrometer with a Cryosphere accessory has been used to study the photochemistry of perennial leaves between 77 K and room temperature.
