Emission spectrum and intensity
steady-state EL/ECL
Material Analysis · Structure & Spectroscopy
Characterise emission spectrum and intensity, external quantum efficiency or luminance where configured, and spatial uniformity, stability, and bias dependence using a scope agreed around your sample and decision.

Common outputs
Fields, conditions, processing and file formats are confirmed before work begins.
Emission spectra reported with the agreed units, sample reference and measurement conditions.
Intensity or luminance versus bias/time supplied in a labelled format suitable for direct sample or condition comparison.
Optional efficiency, map, or decay results provided with the processing basis and quality checks agreed during technical review.
Processed spectra included when selected in the confirmed reporting scope.
Sample requirements
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. |
| Biological / soft material | Provide fixed, preserved or otherwise stabilised material in the agreed container and medium. | Declare biological hazards and confirm fixation, dehydration, temperature and disposal requirements. |
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
Short answers to issues that can change preparation, scope, timing or interpretation.
Provide powder / particles, film / coating, liquid / solution, biological / soft material as applicable. Exact quantity, dimensions and preparation are confirmed during technical review.
Choose the mode around the decision you need to make. For emission spectrum and intensity, start with steady-state EL/ECL; add spatial imaging when comparison or quantification is required.
Typical turnaround is 6 working days after sample acceptance and method confirmation.
Contact resistance, device heating, geometry, and calibration affect quantitative results. Testing may permanently change unstable devices.
