| 1 | Tunable luminescent CsPb_2Br_5 nanoplatelets:applications in light-emitting diodes and photodetectors显示文摘Unlike organic–inorganic hybrid perovskites, all-inorganic cesium lead halide perovskites hold great promise for developing high-performance optoelectronic devices, owing to their improved stability. Herein, we investigate the perovskite-related CsPb_2 Br_5 nanoplatelets(NPLs) with tunable emission wavelengths via changing the reaction temperatures to 100°C, 120°C, and 140°C. Reaction temperature plays a key role in determining the shapes and thicknesses of the resulting CsPb_2 Br_5 NPLs. A higher temperature is in favor of the formation of smaller and thicker NPLs. To develop their potential applications in optoelectronic devices, green light emitting diodes(LEDs) and photodetectors based on CsPb_2 Br_5 NPLs are fabricated. The green LEDs based on CsPb_2 Br_5 NPLs synthesized at 140°C exhibit an excellent pure green emission(full width at half-maximum of <20 nm) and display a luminous efficiency of 34.49 lm∕W under an operation current of 10 m A. Moreover, the photodetector based on CsPb_2 Br_5 NPLs synthesized at 100°C has better performance with a rise time of 0.426 s, a decay time of0.422 s, and a ratio of the current(with and without irradiation) of 364%. | CENG HAN CUNLONG LI ZHIGANG ZANG MING WANG KUAN SUN XIAOSHENG TANG JIHE DU | 2017 | Photonics Research2017，5，5： | 4 |
| 3 | Tweety-Homolog 1 Facilitates Pain via Enhancement of Nociceptor Excitability and Spinal Synaptic Transmission显示文摘Tweety-homolog 1(Ttyh1)is expressed in neural tissue and has been implicated in the generation of several brain diseases.However,its functional significance in pain processing is not understood.By disrupting the gene encoding Ttyh1,we found a loss of Ttyh1 in nociceptors and their central terminals in Ttyh1-deficient mice,along with a reduction in nociceptor excitability and synaptic transmission at identified synapses between nociceptors and spinal neurons projecting to the periaqueductal grey(PAG)in the basal state.More importantly,the peripheral inflammationevoked nociceptor hyperexcitability and spinal synaptic potentiation recorded in spinal-PAG projection neurons were compromised in Ttyh1-deficient mice.Analysis of the paired-pulse ratio and miniature excitatory postsynaptic currents indicated a role of presynaptic Ttyh1 from spinal nociceptor terminals in the regulation of neurotransmitter release.Interfering with Ttyh1 specifically in nociceptors produces a comparable pain relief.Thus,in this study we demonstrated that Ttyh1 is a critical determinant of acute nociception and pain sensitization caused by peripheral inflammation. | Wen-Juan Han Sui-Bin Ma Wen-Bin Wu Fu-Dong Wang Xiu-Li Cao Dong-Hao Wang Hai-Ning Wu Rou-Gang Xie Zhen-Zhen Li Fei Wang Sheng-Xi Wu Min-Hua Zheng Ceng Luo Hua Han | 2021 | Neuroscience Bulletin2021，37，4： | 1 |
