Data Analysis

The maximum emission wavelength over time is shown above. The maximum emission spikes after the first time point and remains approximately constant for the rest of the run.

The integrated emission over time is shown above. The integrated emission reaches a maximum around 1000 s. then slowly decreases until 5000 s. until it begins to increase for the rest of the run.

Selected scans in the first 900 seconds are shown. Emission intensity is seen to increase over time.

Selected scans from 1080-4500 s. are shown. Emission intensity is seen to decrease over this time range.

Selected scans from 4680-10800 s. are shown. Emission intensity is seen to slightly increase over this time range.
