1. Piezoluminescence:experimental data analysis Maciej Grzesiak, Jadwiga Jeziorska, Tomasz Ostafin Opole University Supervisor: mgr Grzegorz Bujnarowski

2. Purpose of the exercise Analysis of mechanical stresses with method of the spectroscopy in tester of ruby subjected to irradiating with bundle of heavy ions of the radiation in the function of the dose absorbed and in the function of the depth.

3. Piezoluminescence Changes in the luminescent radiation triggered with mechanical stresses. It manifesting through the appearance in the spectra of additional lines or strips (with additional centres of the luminescence e.g. vacancies ). These stresses influence to existing spectral lines which can cause shift them.

7. Principle of confocal laser scanning microscope A laser beam passes a light source aperture, then is focused by an objective lens into a small focal volume within a fluorescent speciment. A beam splitter separated the light mixture by allowing only the laser light to pass through and reflecting the fluorescent light intothe detection appararus. After passing a aperture the fluorescent light is detected

8. Curve of the temperature relation for tester of ruby which for calibrating of curves served for two temperatures it is of liquefied nitrogen (77.35 K) and for room temperature (293 K). Spectre of tester of aroused ruby with laser lighting for two exchanged temperatures.

9. Model spectrum at the temperature of 77,35 degrees (Kelvin). As you can see maxsimum of the R2 peak is about 14460,19 cm -1, which is correct with results shown for the temperature’s model spectrum. R2 peak max The graph describing the change of the amplitude and shift spectral lines triggered with rise of heavy ion’s dose.

10. R2 peak R2 peak is about 14442,943 cm-1, which is correct with results shown for the temperature’s model spectrum. Model spectrum in the room temperature The graph describing the change of the amplitude depending on depth

11. This graph is presenting a dependence of the tension on an accepted dose of radiation. On this slide we can see a change of putting the maximum of the R2 depending on the depth
