Summary: Nickel titanate is a yellow-brown pigment with a crystal structure similar to corundum and hematite. It has been found that nickel titanate can change its color with temperature, exhibiting thermochromic properties. The powders were synthesized using a modified Pechini method and then subjected to calcination at 700 degrees C. The thermochromic behavior in the temperature range of 20 degrees C to 400 degrees C was studied by determining the colorimetric L*a*b* parameters. The hue continuously shifts from yellow-brown to red-brown, with L*a*b* parameters changing from 60.4/19.2/58.5 to 42.9/30.5/43.1. It was also observed that the transparency window shifted from 550-650 nm at room temperature to 575-650 nm at 400 degrees C, explaining the color change. Additionally, the effects of Cu or Co doping on the optical and thermochromic properties of nickel titanate were investigated.

Summary: Germanates of EuKGe2O6-, Ca3Fe2Ge3O12-, and BaCu2Ge2O7-types were synthesized using a conventional solid-state method, revealing different oxide-ion conductivity properties. EuKGe2O6 materials exhibit high oxide-ion conductivity, while Ca3Fe2Ge3O12 and BaCu2Ge2O7 materials exhibit mixed electron-/oxide-ion conduction. Doping-induced impurity phases decrease the amount of oxide-ion carriers in the germanates.

Summary: Transparent electrodes (TEs) are crucial for organic optoelectronic devices, but the traditional ITO material is expensive and lacks mechanical performance. New TE materials, including graphene, ultrathin metal, and metal oxide, have emerged to overcome this deficiency. By controlling the fabrication techniques, the conductivity, transmittance, and mechanical stability of these materials have been studied, and their applicability in optoelectronic devices has been reported. This work summarizes the recent progress of TE materials in optoelectronic devices, focusing on their fabrication, properties, and performance. The advantages and limitations of these materials as TEs are summarized, and future development aspects are pointed out to guide the design and fabrication of TE materials for the next generation of transparent optoelectronic devices.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
