求英语牛人帮忙翻译一段化学类英文
After the innovative work of Kasuga et al. [1], titanium dioxide
and titanate nanotubes (TNTs) with large specific surface area and
pore volume have gained promising and important prospect due to
their fascinating microstructures and excellent properties. Titania
and TNTs are particularly interesting partly because they have large
specific surface area, leading to a higher potential of applications
in catalysis [2], semiconductor device [3], and photovoltaic cell [4].
Additionally, the issues like structure stability and corresponding
crystalline phases at various synthesis temperatures remain to be
addressed fromthe point of the view of practical application [5–9].
Rare earth ions have been widely used in high-performance
luminescence devices, catalysts and other functional materials
because of the electronic, optical and chemical characteristics originating
fromtheir 4f electrons [10]. The red luminescence of Eu3+ ion
has been extensively used in the lighting and displays for its distinct
4f–4f transitions. The f-electrons of Eu3+ ions arewell shielded from
the chemical environment and own almost retained atomic character
[11]. In consequence, the f–f emission spectra of Eu3+ consist
of sharp lines.
Rare earth titanates have interesting dielectric, piezoelectric and
ferroelectric properties [12–14]. These materials usually possess
a pyrochlore structure [15–18], which find numerous applications
such as hosts for fluorescence centers, high temperature pigments,
catalysts, thermal barrier coatings, and ionic/electronic conductors,etc. [19–21]. In order to produce new light conversion molecular
devices LCMDs [22] with high thermal stability and processability
in comparison with traditional lanthanide complexes, Eu(III)
titanates have been adopted [23], which were shown to have efficient
red-light emission in the UV irradiation. These phosphors are
relatively stable and have strong absorption in the UV region.
To date, the synthetic routes for TNTs have always been complex
and time-consuming, and furthermore, reports on the synthesis
of Eu(III) titanates nanotubes by the same method are scarce.
In addition, little work has been focused on the study of the
photoluminescence properties of these novel one-dimensional
nanostructures. Nevertheless, it still remains a challenge to investigate
the relationship between luminescence and nanostructure of
Eu(III) titanates.
In thiswork,we report that Eu(III) titanate (Eu2Ti2O7) nanotubes
have been successfully synthesized fromsheet titanate (NaEuTiO4)
by hydrothermal method at various reaction temperatures ranging
from 110 to 150 ◦C. Moreover, the photoluminescence of Eu(III)
titanate (Eu2Ti2O7) nanotubes synthesized at various hydrothermal
temperatures have been investigated.
