“…Then the defect structure, spectroscopy and optical properties were investigated [60,61,62]. Dissimilar to Mg 2+ (or Zn 2+ , In 3+ ) and Fe co-doped LiNbO 3 crystals [63,64], Fe ions still remain at Li sites in LiNbO 3 :Hf,Fe crystals when the HfO 2 -doping concentration goes above its threshold value.…”

The recent advances in the photorefraction of doped lithium niobate crystals are reviewed. Materials have always been the main obstacle for commercial applications of photorefractive holographic storage. Though iron-doped LiNbO3 is the mainstay of holographic data storage efforts, several shortcomings, especially the low response speed, impede it from becoming a commercial recording medium. This paper reviews the photorefractive characteristics of different dopants, especially tetravalent ions, doped and co-doped LiNbO3 crystals, including Hf, Zr and Sn monodoped LiNbO3, Hf and Fe, Zr and Fe doubly doped LiNbO3, Zr, Fe and Mn, Zr, Cu and Ce triply doped LiNbO3, Ru doped LiNbO3, and V and Mo monodoped LiNbO3. Among them, Zr, Fe and Mn triply doped LiNbO3 shows excellent nonvolatile holographic storage properties, and V and Mo monodoped LiNbO3 has fast response and multi-wavelength storage characteristics.

“…In the past few decades, more and more dielectric materials have been applied to holographic volume storage, such as Bi 12 SiO 20 , BaTiO 3 , and LiNbO 3 . Due to better nonlinear optical, electro‐optic, acoustic‐optical, ferroelectric, and photorefractive properties, LiNbO 3 crystals stand out in these dielectric materials. Recently, being a favorable material for holographic storage application, co‐doped Fe:Cu:LiNbO 3 crystal has attracted extensive interest .…”

A series of Hf:Fe:Cu:LiNbO3 crystal with various concentrations of Hf 4+ ion doping are grown in air by the conventional Czochralski technique. The segregation coefficients of the Hf 4+, Fe3+, and Cu2+ ions in the crystals are carried out with an inductively coupled plasma‐atomic emission spectrometer. The birefringence gradient method is measured in order to analyze the optical homogeneity of Hf:Fe:Cu:LiNbO3 crystals. The holographic storage properties of Hf:Fe:Cu:LiNbO3 crystals are investigated by the two‐wavelength coupling experiment. The result shows that the writing time constant shortens from 529.3 to 214.4 s, and the dynamic range increases from 1.12 to 8.07 with increasing Hf 4+ content in the Hf:Fe:Cu:LiNbO3 crystals.

Mesoporous single-crystal ZnO nanobelts: supported preparation and patterning

et al. 2013

We demonstrate that highly porous ZnO nanobelts can be prepared by thermally decomposing ZnS(en)(0.5) hybrid nanobelts (NBs) synthesized through a solvothermal route using Zn layers deposited on alumina substrates as both the Zn substrate and source. Hybrid decomposition by thermal annealing at 400 °C gives porous ZnS NBs that are transformed by further annealing at 600 °C into wurtzite single crystal ZnO nanobelts with an axial direction of [0001]. The evolution of the morphological and structural transformation ZnS(en)(0.5)→ ZnS → ZnO is investigated at the nanoscale by transmission and scanning electron microscopy analyses. Control of the ZnO NB distributions by patterning the Zn metallization on alumina is achieved as a consequence of the parent hybrid NB patterned growth. The presence of NBs on alumina in a ∼100 μm wide region between Zn stripes allows us to fabricate two contact devices where contact pads are electrically connected through a porous ZnO NB entanglement. Such devices are suitable for employment in photodetectors as well as in gas and humidity sensors.
