Notes
  • Thin films of thulium- and samarium-doped AlN are deposited on silicon (111) substrates at 77 K by RF magnetron sputtering method. 200â400 nm thick films are grown at 100â200 watts RF power and 5â8 mTorr nitrogen, using a metal target of Al with Tm and Sm separately. X-rays diffraction results show that films are amorphous. Cathodoluminescence studies are performed at room temperature and two dominant peaks are observed in Tm at 467 nm from 1D2 â 3F4 transition and 480 nm from 1G4 to the ground state 3H6 transition. Other peaks in the visible region are obtained at 650 nm and 685 nm due to 1G4 â 3F4 and 1D2 â 3H4 transitions. Peaks in the ultraviolet and infrared region are also obtained at 371 nm and 802 nm as a result from 1D2 â 3H6 and 3H4 â 3H6 transition, respectively. Sm gives four peaks at 564 nm, 600 nm, 648 nm and 707 nm as a result of 4G5/​2 â 6H5/​2, 4G5/​2 â 6H7/​2, 4G5/​2 â 6H9/​2 and 4G5/​2 â 6H11/​2 transitions. Films are thermally annealed at 1200 K for half an hour in a nitrogen atmosphere. Thermal annealing enhances the intensity of luminescence.
