“…In our experiment, the optimal doping concentration, for the green emission, is x = 0.1, whereas for the red one it is over 0.46 mol, which is much higher than that in other perovskite hosts (most of them below 0.01 mol 41 ). The high concentration of Er 3+ ions can increase the ions number of absorbing pumping source and promote the energy transfer between neighboring Er 3+ ions excited to intermediate energy level, which is important to get higher upconversion efficiency when excited by 980 nm laser.…”

“…[27][28][29] Oxide materials are usually chemically, mechanically, and thermally stable, and therefore can be promising hosts for light UC applications. [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] For these purposes, Er doped many oxide hosts UC materials have been designed and prepared, such as ZnO, 27 43 and NaNbO 3 44 have been studied. However, these types of pervoskite oxides have chemical and physical stability but low emission efficiency due to their low solubility of trivalent rare earth ions.…”

“…However, these types of pervoskite oxides have chemical and physical stability but low emission efficiency due to their low solubility of trivalent rare earth ions. 41 [45][46][47][48] In this case, after activator or/and sensitizer ions substitutions, Bi 4 Ti 3 O 14 thin films show novel UC properties while retaining strong ferroelectric functions, which has potential applications in future integrated optoelectronic devices. So is of interest and significance to study UC properties of rare earth doped BLSFs oxides with big number of m (= 4) such as SBT, which including SrTiO 3 and Bi 4 Ti 3 O 12 units.…”

Er3+ doped SrBi4Ti4O15 (SBT) bismuth layered-structure ferroelectric ceramics were synthesized by the traditional solid-state method, and their upconversion photoluminescent (UC) properties were investigated as a function of Er3+ concentration and incident pump power. Green (555 nm) and red (670 nm) emission bands were obtained under 980 nm excitation at room temperature, which corresponded to the radiative transitions from 4S3/2, and 4F9/2 to 4I15/2, respectively. The emission color of the samples could be changed with moderating the doping concentrations. The dependence of UC intensity on pumping power indicated a two-photon emission process. Studies on dielectric properties indicated that the introduction of Er increased the ferroelectric-paraelectric phase transition temperature (Tc) of SBT, thus making this ceramic suitable for piezoelectric sensor applications at higher temperatures. Piezoelectric measurement showed that the doped SBT had a relative higher piezoelectric constant d33 compared with the non-doped ceramics. The thermal annealing behaviors of the doped sample revealed a stable piezoelectric property. The doped SBT showed bright UC emission while simultaneously having increased Tc and d33. As a multifunctional material, Er doped SBT ferroelectric oxide showed great potential in application of sensor, future optical-electro integration and coupling devices

“…17 We have previously observed that the temperature dependence of UC emission in Er 3þ -doped BTO powders is associated with phase transitions of BTO host. 18 Recently, we have presented an approach to enhance and modulate UC emission through applying a relatively low bias voltage to the Ln 3þ -doped BTO thin film. 19 The realization of UC emission in Ln 3þ -doped ferroelectric materials provides us an opportunity to develop a class of "smart" materials with luminescence properties that change in response to external stimuli including electric field, mechanical force, temperature, and so on.…”

Tunable upconversion (UC) multicolor luminescence is observed from Yb 3þ , Er 3þ , and Tm 3þ tri-doped ferroelectric BaTiO 3 (BTO) materials. By control of dopant concentrations, the lanthanide-doped BTO powders are capable of generating various UC spectra and color tunability. A white-light emission is achieved through an optimal design. Strong UC luminescence is also observed in the lanthanide-doped BTO thin-films grown on Pt/TiO 2 /SiO 2 /Si substrate, which can retain well-defined hysteresis loops with a remnant polarization (2P r ) of 17.8 lC/cm 2 . These findings open the possibility of lanthanide-doped BTO as multifunctional materials, in which both luminescent and ferroelectric properties co-exist. V C 2013 AIP Publishing LLC.

Piezoelectric and ferroelectric materials have shown great potential for control of the optical process in emerging materials. There are three ways for them to impact on the optical process in various materials. They can act as external perturbations, such as ferroelectric gating and piezoelectric strain, to tune the optical properties of the materials and devices. Second, ferroelectricity and piezoelectricity as innate attributes may exist in some optoelectronic materials, which can couple with other functional features (e.g., semiconductor transport, photoexcitation, and photovoltaics) in the materials giving rise to unprecedented device characteristics. The last way is artificially introducing optical functionalities into ferroelectric and piezoelectric materials and devices, which provides an opportunity for investigating the intriguing interplay between the parameters (e.g., electric field, temperature, and strain) and the introduced optical properties. Here, the tuning strategies, fundamental mechanisms, and recent progress in ferroelectric and piezoelectric effects modulating the optical properties of a wide spectrum of materials, including lanthanide-doped phosphors, quantum dots, 2D materials, wurtzite-type semiconductors, and hybrid perovskites, are presented. Finally, the future outlook and challenges of this exciting field are suggested.
