Ba9Lu2Si6O24:Ce3+: An Efficient Green Phosphor with High Thermal and Radiation Stability for Solid-State Lighting
Yongfu Liu,Jianxin Zhang,Jianxin Zhang,Changhua Zhang,Changhua Zhang,Jingtao Xu,Guo-Qiang Liu,Jun Jiang,Haochuan Jiang +8 more
TL;DR: In this paper, a novel orthosilicate green phosphor, Ba9Lu2Si6O24:Ce3+, is synthesized via a simple solid-state reaction, which exhibits a broad emission band with a width of nearly 120 nm, peaking at 490 nm.
Journal ArticleDOI
Valence band engineering and thermoelectric performance optimization in SnTe by Mn-alloying via a zone-melting method
Jun He,Jun He,Xiaojian Tan,Jingtao Xu,Guo-Qiang Liu,Hezhu Shao,Yajie Fu,Xue Wang,Liu Zhu,Jiaqiang Xu,Haochuan Jiang,Jun Jiang +11 more
TL;DR: In this paper, the authors show that zone-melted SnTe systems with additional Mn (1−7 mol%) can control the hole concentration by reducing the Sn vacancies, and modulate the electronic band structure by increasing the band gap and decreasing the energy separation between the light and heavy hole valence bands.
Journal ArticleDOI
Enhanced thermoelectric performance in p-type polycrystalline SnSe benefiting from texture modulation
Yajie Fu,Yajie Fu,Jingtao Xu,Guo-Qiang Liu,Jingkai Yang,Xiaojian Tan,Liu Zhu,Haiming Qin,Hezhu Shao,Haochuan Jiang,Bo Liang,Jun Jiang +11 more
TL;DR: In this article, a zone melting method is employed to prepare polycrystalline SnSe samples, which show highly textured structures and strong anisotropic thermoelectric performance.
Journal ArticleDOI
Coulomb-enhanced spin-orbit splitting: the missing piece in the Sr2RhO4 puzzle.
TL;DR: The outstanding discrepancy between the measured and calculated Fermi surfaces in the well-characterized, paramagnetic FermI liquid Sr2RhO4 is resolved by including the spin-orbit coupling and Coulomb repulsion, resulting in an effective spin- orbit coupling constant enhanced 2.15 times over the bare value.
Journal ArticleDOI
Band engineering and improved thermoelectric performance in M-doped SnTe (M = Mg, Mn, Cd, and Hg)
TL;DR: Owing to the improved Seebeck coefficients, Mn- and Cd-doped SnTe exhibit promising thermoelectric properties with ZT = 1.32 and 1.65 at around 800 K, respectively.
