Analysis
Fluorescence Spectroscopy Analysis
Excitation–emission spectroscopy to characterise the optical properties of fluorescent materials, quantum dots, phosphors, dyes and biological probes.
In short
Excitation–emission spectroscopy to characterise the optical properties of fluorescent materials, quantum dots, phosphors, dyes and biological probes. Fluorescence spectroscopy analysis on a PerkinElmer FL 8500 spectrofluorometer records excitation and emission spectra of solutions, powders and thin films. Emission maxima, Stokes shift, bandwidth and relative intensity are determined, and three-dimensional excitation–emission matrices (EEM) distinguish fluorophores in complex mixtures.
Fluorescence spectroscopy analysis on a PerkinElmer FL 8500 spectrofluorometer records excitation and emission spectra of solutions, powders and thin films. Emission maxima, Stokes shift, bandwidth and relative intensity are determined, and three-dimensional excitation–emission matrices (EEM) distinguish fluorophores in complex mixtures. Relative quantum yield can be calculated against a reference standard, and concentration-dependent quenching as well as temperature or pH effects can be followed. Typical questions include emission quality in quantum dot and carbon dot synthesis, characterisation of phosphors and lighting materials, screening of fluorescent contaminants in dyes and pigments, and evaluation of pharmaceutical and biological probe formulations. The service addresses nanomaterials, optoelectronics, pharmaceutical, food and environmental organisations and academic groups.

How it works
Request and scoping
Sample form, expected excitation/emission region, solvent and concentration are agreed; conditions avoiding inner-filter effects are planned.
Sample reception and preparation
Samples are logged; solutions are diluted into suitable cuvettes, while powders and films are mounted in the solid sample holder.
Measurement
Excitation and emission scans are recorded with optimised slit and gain settings; solvent blanks and reference standards are included.
Reporting
Results are presented in the standard analysis report; supporting technical documentation is shared on request.
