Why this service
What PL/TRPL/EEM can help you understand
Photoluminescence and Steady-State/Time-Resolved Fluorescence Spectroscopy is selected when the project needs defensible information on emission or transient spectrum, excited-state lifetime and…
Excited-state lifetime and kinetics
time-correlated or streak-camera emission
Quantum yield, energy transfer, trapping, or recombination
pump-probe transient absorption
Choose the scope
Start from the question, not the tool
The method, preparation route and reporting depth depend on what you need to decide.
Steady-state PL

Pump-probe transient absorption
quantum yield, energy transfer, trapping, or recombination
- Best used when
- quantum yield, energy transfer, trapping, or recombination
- Typical result
- Optional quantum yield, map, or global-analysis parameters

Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
Steady-state or transient spectra reported with the agreed units, sample reference and measurement conditions.
Decay/kinetic traces and fitted lifetimes supplied in a labelled format suitable for direct sample or condition comparison.
Optional quantum yield, map, or global-analysis parameters provided with the processing basis and quality checks agreed during technical review.
Processed spectra included when selected in the confirmed reporting scope.
Sample requirements
What to provide before work begins
Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.
| Suitable sample | Submission requirement | Planning note |
|---|---|---|
| Powder / particles | Provide a dry, homogeneous and clearly labelled sample in a sealed container. | Exact mass and any drying or dispersion step are confirmed after technical review. |
| Film / coating | Provide the coated substrate or a flat film with the test surface and coating side clearly marked. | State the substrate, nominal thickness and whether sectioning or mounting is permitted. |
| Liquid / solution | Provide a sealed, compatible container labelled with composition, concentration and solvent. | Declare volatility, corrosivity, suspended solids and any storage or temperature requirement. |
| Device / assembly | Provide a complete labelled device or assembly with drawings, interfaces and operating limits. | Confirm power, connections, operating state, access restrictions and permitted disassembly. |
Objective: state the decision, comparison or acceptance criterion the work must support.
Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.
Questions and answers
Common planning decisions
Short answers to issues that can change preparation, scope, timing or interpretation.
What should I send for Photoluminescence and Steady-State/Time-Resolved Fluorescence Spectroscopy?
Provide powder / particles, film / coating, liquid / solution, device / assembly as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.
Which analysis option should I choose?
Choose the mode around the decision you need to make. For emission or transient spectrum, start with steady-state PL; add time-correlated or streak-camera emission when comparison or quantification is required.
How long will the test take?
Typical turnaround is 6 working days after sample acceptance and method confirmation.
What can limit the result?
Inner-filter effects, reabsorption, scattering, and instrument response can distort results. Kinetic models are not unique without sufficient spectral and temporal coverage.
