The spectrally narrow, long-lived luminescence of lanthanide ions makes optical
nanomaterials based on these elements uniquely attractive from both a fundamental and …

Windows play significant roles in today's buildings, allowing outside view and providing
occupants with daylight. However, windows are also often considered to be one of the …

In the past century, ferroelectrics are well known in electroceramics and microelectronics for
their unique ferroelectric, piezoelectric, pyroelectric, and photovoltaic effects. Nowadays, the …

Dual-band electrochromic materials are integral to the development of smart windows where
visible and near-infrared (NIR) light transmittance may be individually controlled. We present …

The band structure of ferroelectrics can be modulated by mechanical stress induced
piezoelectric polarization charges, and thus to promote the separation of photo-excited …

Antiferroelectric materials are promising to be used for power capacitive devices. To improve
the energy storage performance, solid-solution and defect engineering are widely used to …

High permittivity materials for a gigahertz (GHz) communication technology have been
actively sought for some time. Unfortunately, in most materials, the dielectric constant starts …

In this work, we report the defect-mediated, abnormal non-linear polarization behavior
observed in centrosymmetric rutile TiO2 where less than 1 at% of sterically mismatched …

Recently, defect complex coupling in nonmagnetic acceptor-donor co-doped binary metal
oxides is found to partially localize the donor electrons with a characteristic defect-dipolar …

This review is focusing on photocatalytic hydrogen (H2) production as a viable fuel. The
limitations of different production methods for H2 generation and the importance of …
