Herein, we present defect-induced photoluminescence behavior of Ga-doped ZnO (GZO)
thin films with varying do** (Ga) concentrations and energetic ion irradiation. The Ga …

A novel type of sub-lattice of the Jahn-Teller (JT) centers was arranged in Ti-doped barium
hexaferrite BaFe12O19. In the un-doped crystal all iron ions, sitting in five different …

Phosphorescence is a basic luminescence phenomenon that is represented by continuous
light emission for a period after materials have absorbed excitation energy. Here, an obvious …

Copper impurities have long been linked with green luminescence (GL) in ZnO. Copper is
known to introduce an acceptor level close to the conduction band of ZnO, and the GL has …

The origin of ZnO radiation resistance is fascinating but still unclear. Herein, we found that
radiation tolerance of ZnO can be tuned by engineering intrinsic defects into the ZnO. The …

Elucidating the property of the polaronic state at ultrafast temporal resolution is of great
significance, especially for photocatalytic and solar-energy materials. In this work …

Tetragonal CsPb2Br5 has attracted tremendous attention due to its high stability and strong
green emission. But its luminescence mechanism has become controversial after it was …

In this article, we demonstrate a novel approach to determine the absorption coefficient of
ZnO below the bandgap via measuring the self-absorption (SA) effect on the two-photon …

In this study, nanoindentation tests at three different strain rates within 100 nm indentation
depth were conducted on an a-plane (11 2¯ 0) ZnO single crystal to investigate the effect of …

This study reports on the successful synthesis of MoO 3-x@ MoS 2 (x= 0, 1) nanostructure
via a one-step hydrothermal combined with the annealing method, which resulted in a well …
