Abstract
Bu çalışmada camların içerisine [Na_2 SO ? _4,[Rb_2 SO ? _4,HgCl_2,MgO,CsBr, K_2 SO_4,Al[(OH) ? _3 ve CdF_2 maddelerinden değişik oranlarda karıştırıldı ve EPR spektrumunda sinyal gözlemek amacıyla Cu^(2+) paramanyetik iyonu katkılandırıldı. Ayrıca camların içine Fe^(3+) paramanyetik iyonu değişik oranlarda katkılandırıldı. Yine aynı şekilde camların içine BaCl_2,HgCl_2 ve Mg_3 (PO_4 )_2 maddelerinden değişik oranlarda karıştırılarak Mn^(2+) paramanyetik iyonu katkılandırıldı. Numuneler 200-400 ? de uçucuların gitmesi için ısıtıldı. Daha sonra numuneler yaklaşık 1000 ? sıcaklıkta eritilip hızlı soğumaya bırakılarak camsı maddeler elde edildi. Cu^(2+) iyonu katkılı camsı maddelerin oda sıcaklığında EPR spektrumları kaydedildi. [Na_2 SO ? _4,[Rb_2 SO ? _4, ve HgCl_2 katkılı camsılarda madde miktarına bağlı olarak spektrumda herhangi bir değişiklik gözlenmezken, MgO,CsBr,K_2 SO_4,Al[(OH) ? _3 ve CdF_2 katkılı camsılarda madde miktarındaki değişime bağlı olarak EPR spektrumlarında değişiklikler gözlendi. Fe^(3+) iyonu katkılı camsı yapılarda yine madde miktarındaki değişiklik ile EPR spektrumlarında değişiklikler gözlendi. Mn^(2+) iyonu katkılı camsı yapılarda madde miktarına bağlı değişiklikler gözlenmezken Fe^(3+) iyonun rezonans sinyali bölgesinde zayıf sinyaller verdiği gözlemlendi.
In this study, [Na_2 SO]_4,[Rb_2 SO]_4,HgCl_2,MgO,CsBr,K_2 SO_4,Al[(OH)]_3 and CdF_2 compounds were mixed with glasses at various ratios and then doped with paramagnetic Cu^(2+) ion in orde to observe signals in EPR spectrum. Paramagnetic ion Fe^(3+) was also doped at various ratios to glasses. In the same manner, BaCl_2,HgCl_2 and Mg_3 (PO_4 )_2 compounds were mixed with glasses at different rates and then paramagnetic Mn^(2+) ion was doped. Next, these samples were heated at 200-400 ?. Glassy states were obtained leaving the samples fast cooling just after melting them at the tempeture about 1000 ?. The states doped with Cu^(2+) ion were investigated by EPR at room temperature. Glasses including [Na_2 SO]_4,[Rb_2 SO]_4 and HgCl_2 compounds showed no change in spectra depending on the sample amount while glasses including MgO,CsBr,K_2 SO_4,Al[(OH)]_3 and CdF_2 compounds were observed changes in spectra with changing sample amount. Also there have been differences in the spectra of glassy states doped with Fe^(3+) ion when there are changes in the amount of matter. There was no change in the spectra of glassy states doped with Mn^(2+) ion depending on the amount of materials. However, weak signals were observed at the resonance region for Fe^(3+) ion.
