Facilities

Optics Laboratory

HORIBA Jobin Yvon FluroLog

Our main fluorescence spectrometer is a J-Y Fluorolog which permits measurement over a range of 200 to 1500 nm, and offers time correlated single photon counting for lifetime measurements. An RMC-22 closed cycle refrigerator permits measurements down to 12K.

We also have a PerkinElmer LS-5B and a PerkinElmer LS 55 spectrofluorimeter. These instruments offer modest resolution (2.5 nm), pulsed excitation over the range 200 - 800 nm, and emission over the range 200 - 750 nm.

For optical absorption spectroscopy, we have a Shimadzu UV-2100 (an earlier version of the Shimadzu UV-3101) double beam spectrometer for ultraviolet (UV) and visible work. We also have access to a range of other UV/visible and infra-red instruments including a Cary 100 UV/visible spectrometer, a PerkinElmer Spectrum One Fourier transform infra-red spectrometer, and a Bruker Tensor 27 infra-red spectrometer.

Thermal analysis laboratory

TA DSC Q100

We have a TA DSC Q100  differential scanning calorimeter which can operate from -130 to 600˚C. This instrument is primarily used for glass thermal analysis.

TA TGA Q600

We also have a TA Q600 thermogravimetric analyser which operates between room temperature and 1500˚C. This instrument is mainly used for thermal analysis associated with the materials preparation aspects of our work. A mass-spectrum analyser is available for analysing exhaust gases from the TA Q600.

Sample preparation laboratory

We have dry-box facilities for preparing hygroscopic samples. Attached to the dry-box is a conventional furnace (20 - 1000°C) and a radio frequency induction furnace (Ameritherm) which both operate with atmospheres of nitrogen or argon. We also have various annealing furnaces, cutting and polishing facilities, and ball mills and a draw-bar coater for powder and screen preparation respectively. We have high temperature oven up to 1500°C as well as access to XRD and electron microscope facilities.
