| dc.description.abstract | Darbā pētīti Oksifluorīdu stiklu keramikas (OxFGC) paraugu spektri ar elektronu paramagnētiskās rezonanses (EPR) metodi. EPR spektri tika uzņemti 7 OxFGC paraugiem ar atšķirīgu izkarsēšanas laiku. Litija Borāta stikla keramikas EPR spektrs sastāv no daudzām EPR joslām, taču neizdevās novērot spektru hipersīkstruktūru. Litija Silikāta stikla keramikas gadījumā ir novērojama EPR spektru hipersīkstruktūra. Mūsu darbā ar datorprogrammas palīdzību tika izrēķināti daži EPR spektri, izmantojot mijiedarbības ar Fluora(F), Litija(Li) un Itrija(Y) kodolu spiniem. Spektri tika salīdzināti ar keramikas EPR spektru hipersīkstruktūru. | en_US |
| dc.description.abstract | In this work Electron paramagnetic resonance (EPR) spectra of oxyfluoride glass ceramic samples were studied. EPR spectra were taken for 7 OxFGC samples which were prepared by heating at different temperatures.
EPR spectra of Lithium borate glass ceramics consist of multiple EPR bands while hyperfine structure of them is not observable. In the case of Lithium silicate glass ceramics there is hf structure of EPR spectra observable. In these studies calculations for some cases using different number of surrounding nuclei: fluorine (F), lithium (Li) and yttrium (Y) were made by means of computer program. Calculated spectra were compared to experimental EPR spectra glass ceramics. | en_US |
