“…10 After sequential absorption of two or more photons via intermediate energy states, the conversion of long wavelength photons into shorter visible wavelengths can be achieved. [11][12][13][14][15][16][17][18] In contrast to the conventional fluorescent emission (down conversion emission), the UC luminescence could significantly minimize autofluorescence background and the photodamage to biological specimens, and achieve high depth penetration in biological tissues through utilizing near infrared (NIR) excitation rather than ultraviolet (UV) excitation. In order to obtained UC luminescence, Er 3+ , Tm 3+ , and Ho 3+ with * Authors to whom correspondence should be addressed.…”

Homogeneously doped Yb3+ and Er3+ cerium-based coordination polymer (CP) microspheres have been successfully synthesized on a large scale through a simple solvothermal route with 2,5-pyridinedicarboxylic acid (2,5-H2PDC) as the organic linker. CeO2: Yb3+, Er3+ porous microspheres were obtained by annealing the corresponding CP microspheres at 600 °C for 4 h under atmospheric pressure. These as-prepared products were characterized by Powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), energy-dispersion X-ray (EDX) spectroscopy, Thermogravimetric (TG) and derivative thermogravimetric (DTG) analysis. The room temperature upconversion luminescent spectra of the as-prepared microspheres were carried out by 980 nm NIR light excitation. Interestingly, Yb3+ and Er3+ codoped CP microspheres give a single-band emission centered at 673 nm, while the CeO2: Yb3+, Er3+ microspheres give emission in green and red region, with red being the dominant emission. The emission intensity of the CeO2: Yb3+, Er3+ microspheres were much stronger than that of the Yb3+ and Er3+ codoped CP microspheres.

“…4,[14][15][16][17] Most of the recent study interest relevant to the host materials was focused on the fluoride glasses due to the low phonon energy of the crystal lattice. 18,19 Nevertheless, less attention has paid to the host of Aurivillius bismuth layered-structure ferroelectrics (BLSFs). Among BLSFs, Bi 5 TiNbWO 15 (BTNW) was typical BLSFs of the intergrowth of Bi 3 TiNbO 9 , which has highest T c , with Bi 2 WO 6 along the c-axis, in which the materials can improve the piezoelectricity retaining a high T c .…”

The Er3+ doped Bi5TiNbWO15 ceramics have been synthesized using conventional solid-state reaction techniques. The crystal structure, ferroelectric properties, UC emission properties and especially the temperature sensing behaviors were systematically studied. With increasing Er3+ content, the investigation of XRD pattern, the ferroelectric loop and the UC emission indicated that the Er3+ ions dopants preferentially substituted the A sites of Bi3TiNbO9 and then Bi2WO6. Based on fluorescence intensity ratio (FIR) technique, the observed results implied the ceramics were promising candidates for temperature sensors in the temperature range of 175 K −550 K. More importantly, this study provided a contrast of temperature sensitivity between emission from the same part (Bi3TiNbO9) in bismuth layered-structure and emission from the different part (Bi3TiNbO9 and Bi2WO6) in bismuth layered-structure for the first time.
