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...

| description | 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 experimental results, the Er3+-related 2H11/2 → 4I15/2 and 4S3/2 → 4I15/2 optical transitions – corresponding to the green region of the visible spectrum of electromagnetic radiation – were highly influenced by the local temperature. Compared with other Er3+-doped materials, the present GeOx:Er film exhibited a rather large 2H11/2-to-4S3/2 energy levels separation, suggesting its potential to act as a very sensitive temperature probe in the ~300–750 K range. Along with the Er3+-related optical emission characteristics, the atomic composition and structure of the GeOx:Er film were also investigated in detail. |
