A sensitive temperature probe based on Er3+-doped GeOx films
The light emission due to Er3+ ions when inserted in a GeOx film was analyzed at different temperatures. The film was prepared by sputtering a combined Ge + Er solid target and the incorporation of oxygen took place by thermal annealing the film under a continuous flow of O2. According to the experi...
