OKSIT CAMLARIN ELEKTRON PARAMENYETIK REZONANS ILEINCELENMESIÖZETBu çalismada oksit camlarin içerisine az miktarda Cu2+, Mn2+, Gd 3+ ve VO2+paramanyetik iyonlari katkilandirarak, elektrikli firinda 800-1000ºC sicaklikta 15dakika süreyle eritildi ve bunun sonucunda çesitli B O3-CdO-PbO camlari elde edildi.2Elde edilen oksit camlarin EPR spektrumlari oda sicakliginda Varian E 102spektrometresiyle çekilerek EPR spektrumlarindan birincil g ve A degerleri ölçüldü. Bug ve A degerleri oksit camlar hakkinda bazi bilgiler elde etmemizi sagladi. Bundanbaska, yüksek miktarda paramanyetik iyon katkilandirilan oksit camlar elde edildi vebunlarin spektrumlari oda sicakliginda çekildi. EPR spektrumlari, oksit camlardakiparamanyetik iyonlarin miktarina göre az yada çok degisiklik gösterdi.
THE INVESTIGATION OF SOME OXIDE GLASSES WITH ELECTRONPARAMAGNETIC RESONANCE SPECTROSCOPYABSTRACTIn this study, small amount of Cu+2 , Mn+2 , Gd +3 , VO +2 paramagnetic ions weredoped in oxide glasses obtained by mixing various amounts of B2 O3 -CdO-PbO andmelting in electrical furnace at 800-1000ºC for 15 minutes. The EPR spectra of theoxide glasses obtained are taken using a Varian E 102E EPR spectrometer at roomtemperature. Principal values of g and A tensors are measured from the EPR spectra.These g and A values give us some information about oxide glasses. Furthermore, oxideglasses with higher amounts of paramagnetic ions are obtained and the spectra of theseare taken at room temperature. EPR spectra change more or less with the amounts ofparamagnetic ion in the oxide glasses.
