The optical magnetic sensor using Er doped TiO2 thin films

摘要：

A TiO2:Er formed on Si substrate by laser ablation. The TiO2:Er shows visible and IR emissions at room temperature. The TiO2:Er thin film was formed on a p-Si (100) substrate by ablating a TiO2:Er ceramic target which is a mixture of TiO2 and prescribed amounts of 1 wt％ Er2O3. The superconducting magnet was used for applied of a magnetic field. Magnetic field intensity was changed from 0.0 T (Tesla) to 7.5 T with PL measurement at room temperature. The sharp intense PL peak at 522.80 nm, 564.36 nm, 667.67 nm, 0.98 μm and 1.53 μm originating from the intra-4f shell transition in Er3+ ions was observed from RT. The spectrum form changes were according to the Zeeman effect with the rise of magnetic field intensity.
