AbstractThe Er3+-Tm3+-Yb3+ tri-codoped Bi4Ti3O12 thin films were prepared by chemical solution deposition method and its upconversion (UC) photoluminescence and ferroelectric properties were studied. There are four emission bands in the visible UC luminescence spectra excited by 980 nm infrared light at room temperature. The 478 nm blue emission band corresponds to (1)G(4) -> H-3(6) transition of Tm3+, and the 527, 548 nm green emission bands correspond to H-2(11/2) -> I-4(15/2) and S-4(3/2) -> I-4(15/2) transitions of Er3+, and the 657 nm red emission band corresponds to F-4(9/2) -> I-4(15/2) transition of Er3+ and (1)G(4) -> F-3(4) transition of Tm3+. The fluorescent color can be tuned by adjusting Er3+, Tm3+ and Yb3+ concentrations. For Bi3 59-lambda ErxTm0 01Yb0 4Ti3O12 (BErxTYT) thin films with fixed Tm3+ and Yb3+ concentrations, the intensity ratio of green and red emissions to blue one gradually increased with the increase of Er3+ concentrations, and the quenching concentration of Er3+ is only about 1.75 % (mole fraction). For Bi-3 593-yEr0.007TmyYb0 4Ti3O12 (BETmyYT) thin films with fixed Er3+ and Yb3+ concentrations, the intensity ratio of green and red emissions to blue one decreased with the increase of Tm3+ concentrations, and Tm3+ quenching concentration is about 2.5 parts per thousand. For Bi3 98-zEr0.01Tm0 01YbzTi3O12 (BETYbzT) thin films with fixed Er3+ and Tm3+ concentrations, the intensity ratio of blue or red emission to green one increase with increase of Yb3+ concentrations, and Yb3+ quenching concentration is less than 5 mol% for the luminescence from Er3+ and lager than 18 mol% for the luminescence from Tm3+. The optimal color coordinate in these films is (0.31, 0.34), close to standard white-light coordinate of (0.33, 0.33), which appears in Bi3 5815Er0.0085Tm0 01Yb0 4Ti3O12 thin film. The color coordinate has only a little change with increasing pumping power, which suggests that luminescence from the thin films has good color stability. There exist significant energy transfers from Er3+ to Tm3+, which will affect the relative intensities of blue, green and red emissions and their quenching concentrations by analyzing the UC emission mechanism of the thin films. The remnant polarization value of the film prepared on Pt/Ti/SiO2/Si substrate reaches the maximum and is equal to 27.8 mu C/cm(2) when the total codoping concentration of Er3+, Tm3+ and Yb3+ is about 10% (Bi3 5815Er0 0085TM0.01Yb0 4Ti3O12 film).
