Optics Laboratory

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

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.

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.

We also have access to our earlier instruments, a Shimadzu DSC-60 for differential scanning calorimetry measurements between –100°C and ~500°C. This is complemented by a Shimadzu TGA-50 for thermal gravimetric analysis between room temperature and 1500°C in flowing argon or air.

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.

Irradiation and Diffraction

We use a Phillips PW 1720 and PW 1730 x-ray generator and a Faxitron 43855A x-ray cabinet for x-irradiations, with a maximum irradiation energy of 55 kV. We also have a de Götzen X-Genus dental x-ray set which provides 70 kV x-rays and a Golden Engineering XR150 portable x-ray generator which produces 150 kV pulses.

Gamma irradiations from 60Co and other radio-nuclide sources are provided by our colleagues at the GNS Science.

We have access to a PANalytical X'Pert Pro Multi Purpose Diffractometer and to electron diffraction on JEOL TEM and SEM instruments in the electron microscope suite.

Facilities at Industrial Research Ltd (IRL)

We have access to a range of experimental facilities at IRL. These include a dry box and furnaces for temperatures up to 1500°C, XRD, optical (visible and FTIR), and fluorescence spectrometers as well as a fully equipped optics lab with lasers ranging from 325 to 1550 nm.

The MacDiarmid Institute SQUID magnetometer (pictured below) is also located at IRL.
