Effect of Co co-doping in Optical Properties of ZnTe:Mn Nanocrystals

06-Dec-2016 | Alessandra Santos Silva; Sidney Alves Lourenço; Marco Aurelio Toledo Silva; Sebastião W. da Silva; Paulo Cesar Morai ..., Physical Chemistry Chemical Physics, 2016

We study the effect of Co co-doping on the optical properties of Mn-doped ZnTe nanocrystals (NCs) embedded in a glass matrix. Optical absorption (OA) and crystal field theory strongly indicated the substitutional incorporation of Co2+ ions in these semiconducting NCs as well as the characteristic ...

[Ti12In6O18(OOCC6H5)30]: a multifunctional hetero-polyoxotitanate nanocluster with high stability and visible photoactivity

06-Dec-2016 | Shengjun Liu; Wei Hu; Jayanta Kr. Nath; Jing Tong; Xudong Hou; Wenlong Liu; Jinlong Yang; Bo Liu, Dalton Transactions, 2016

We present a novel strategy to improve the stability and optical absorption of polyoxotitanates (POTs) via concurrently fully carboxylate-coordinating and hetero-metal-doping, and illustrate the strategy by an indium doped hetero-polyoxotitanate (h-POT) of a [Ti12In6O18(OOCC6H5)30] (POTi12In6) ...

Improved microwave absorption performance of modified SiC in the 2–18 GHz frequency range

06-Dec-2016 | Junhong Chen; Meng Liu; Tao Yang; Famin Zhai; Xin-mei Hou; Kuo-Chih Chou, CrystEngComm, 2016

Aiming to improve the microwave absorption performance of SiC, various methods including doping and changing the shape were adopted. In view of doping, B-doped silicon carbide (B-SiC) with the B content of 3 mass% were prepared via a simple carbothermal reduction method. By using different raw ...

Improving the charge carrier transport of organic solar cells by incorporating a deep energy level molecule

06-Dec-2016 | Chunyu Liu; Zhiqi Li; Zhihui Zhang; Xinyuan Zhang; Liang Shen; Wenbin Guo; Liu Zhang; Yongbing Long; Shengping Ruan, Physical Chemistry Chemical Physics, 2016

Tetrafluoro-tetracyanoquinodimethane (F4-TCNQ), a strong molecular acceptor, has been proved to be an excellent candidate to achieve the p-type doping effect. When F4-TCNQ is incorporated into a poly(3-hexylthiophene) (P3HT): indene-C60 bisadduct (ICBA) active layer, superior behavior upon ...

Hydrogen Treatment as a Detergent of Electronic Trap States in Lead Chalcogenide Nanoparticles

02-Dec-2016 | Márton Vörös; Nicholas P. Brawand; Giulia Galli, Chemistry of Materials, 2016

Lead chalcogenide (PbX) nanoparticles are promising materials for solar energy conversion. However, the presence of trap states in their electronic gap limits their usability, and developing a universal strategy to remove trap states is a persistent challenge. Using calculations based on density ...
