“…However, the grain sizes of the ZAuB‐0 and ZAuB‐3 nanocomposites in Figure G,H are much larger than those of the pure BET without ZnO nanorods. As previous reports, the reason is that the surfaces of the ZnO nanorods act as seeding crystallites to promote the nucleation and growth of BET . Figure I‐K show the cross‐sectional SEM images of the BET, ZAuB‐0 and ZAuB‐3.…”

“…So, the red photolumincence enhancement of Eu 3+ ions is achieved by the energy transfer from ZnO‐Au to BET, and the Eu 3+ ions PL enhancement is highly dependent on the NBE emission intensity, namely the Au content in Au‐ZnO/BET films. In addition, the crystallization enhancement of the composite thin films shown in the SEM measurements (Figure F‐H) also contributes to the increase in the luminescence of the Eu 3+ ions …”

“…In addition, the crystallization enhancement of the composite thin films shown in the SEM measurements ( Figure 1F-H) also contributes to the increase in the luminescence of the Eu 3+ ions. 11,19 The schematic diagram for electrical properties measurement is shown in Figure 5A. As well as Figure 5B shows the dielectric properties of BET, ZAuB-0, and ZAuB-3 nanocomposite films on Pt/TiO 2 /SiO 2 /Si substrates, increasing from 275 to 340 (at 1 kHz).…”

“…As previous reports, the reason is that the surfaces of the ZnO nanorods act as seeding crystallites to promote the nucleation and growth of BET. 11,19 Figure 1I-K show the cross-sectional SEM images of the BET, ZAuB-0 and ZAuB-3. In comparison with the pure ZnO nanorods, the edges of the ZnO nanorods in the composite films are obscure, which indicates that the BET firstly fills in the gaps between ZnO nanorods and then grows on the top.…”

“…The typical PL spectrum of ZnO consists of a sharp NBE emission in the ultraviolet (UV) region and a broad deep‐level (DL) emission band in the visible green/yellow/red region . In the previous reports, it is suggested that an efficient energy transfer between ZnO and Eu 3+ ions is responsible for the PL enhancement for ZnO/BET composited films. Especially, the tenfold PL enhancement in the c ‐axis‐oriented ZnO nanorods and BET composited films on the Si substrates is obtained by the energy transfer process .…”

This paper firstly reports on a series of nanocomposite thin films composed of a ferroelectric Bi3.6Eu0.4Ti3O12 (BET) and Au‐decorated ZnO nanorods (Au‐ZnO), which are prepared by a ultraviolet‐induced hybrid chemical solution method. The effects of Au nanoparticles (NPs) and ZnO nanorods on the significantly red photoluminescence enhancement of Eu3+ ions are investigated. The results indicate that the larger near band edge (NBE) emission of ZnO by the SPR effect of Au NPs can make an energy transfer from ZnO to Eu3+ ions. Simultaneously, the depression of the deep‐level emission of ZnO can improve the monochromaticity in the visible range. Furthermore, the dielectric and ferroelectric properties of the thin films are also enhanced. The findings suggest that the nanocomposite thin films of a ferroelectric BET and Au‐ZnO could be used as a multifunctional material in the ferroelectric optoelectronic devices with bright light emitting.

Rare earth doping is an important method to improve the properties of optoelectronic functional materials. Combining rare earth doping ferroelectric materials and rare earth photoluminescence can create new functional properties of ferroelectric materials. For example, choosing and using an appropriate rare earth element to be doped into a bismuth titanate ferroelectric material, the bismuth titanate will exhibit good photoluminescent properties as well as ferroelectric properties. Recently, photoluminescence properties originating from rare earth ions in oxide ferroelectric materials have attracted much attention for possible integrated photoluminescent ferroelectric device applications. In this paper, we briefly review the research status and progress of photoluminescence in rare earth photoluminescent ferroelectric materials, and we place the emphasis on our own research work in photoluminescent ferroelectric thin films such as (Bi,Eu)4Ti3O12, (Bi,Er)4Ti3O12, and codoped bismuth titanate thin films, and nanocomposite (Bi,Eu)4Ti3O12 ferroelectric thin films. Our results show that the rare earth doped bismuth titanate ferroelectric thin films exhibit good photoluminescent and ferroelectric properties due to unique compositions and layered perovskite structure, that the Eu3+ fluorescent structure probe can provide a new path for further studying the relationship between structure and property of Eu-doped ferroelectric thin films, that the rare earth photoluminescence can be used to examine the existence of morphotropic phase boundary in certain ferroelectric thin films such as Pr-doped x(K1/2Bi1/2)TiO3-(1－x)(Na1/2Bi1/2)TiO3 thin films, and nanocomposite materials of ZnO nanomaterials, and that Au nanoparticles, Ag nanoparticles with Eu-doped bismuth titanate exhibit obviously enhanced photoluminescent properties.
