Abstract :
A TiO2:Nd formed on Si(100) substrate by laser ablation. The TiO2:Nd shows IR emissions at room temperature. The superconducting magnet was used for applied of a magnetic field. Magnetic field intensity was changed from 0.0 T (Tesla) to 8.0 T with PL measurement at room temperature. The sharp intense PL peak at 913.5 nm, 933.3 nm, 954.6 nm, 1093.7 nm and 1382.7 nm originating from the intra-4f shell transition in Nd3+ ions was observed. The spectrum form change was according to the Zeeman effect with the rise of magnetic field intensity.
