Abstract
Bakalaura darbā tika pētīta talliju saturošu augstfrekvences bezelektrodu lampu pildījuma ietekme uz to spektru. Lai to izdarītu, tika analizētas tallija un argona spektrāllīniju intensitātes izmaiņas atkarībā no ierosmes ģeneratora sprieguma, kā arī pētīta to stabilitāte laikā. Tāpat tika novērtēta palīgelementu – antimona un joda - ietekme uz starojuma spektra intensitāti un stabilitāti. Izmantojot hidroksilradikāļa OH rotācijas joslu spektru, tika noteikta gāzes temperatūra. Darbā iegūtajos rezultātos var novērot, ka, palielinot ģeneratora spriegumu, tallija spektrālo līniju relatīvā intensitāte strauji pieaug un ka antimona pievienošana lampā būtiski ietekmē spektrālo līniju relatīvo intensitāti un starojuma stabilitāti.
In this bachelor’s thesis the influence of light source filling on the radiation spectra of high-frequency electrodeless lamps were investigated. Intensity changes of several thallium and argon spectral lines, as well as their stability over time, were analyzed in dependence on excitation generator voltage. Also influence of additional elements – antimonium and iodine – was analyzed. Hidroxylradical OH rotational spectrum was used to determine gas temperature. Results obtained showed that relative intensity of thallium spectral lines increases rapidly, when voltage of generator is increased and that by adding antimony in the lamps fillings have significantly affects to relative intensity of the spectral lines as well as radiation stability.
