Impurity-trapped excitons and electron traps in CaF$_2$:Yb$^{2+}$ and SrF$_2$:Yb$^{2+}$ probed by transient photoluminescence enhancement
rare-earth Yb2+ CaF2 two-color spectroscopy exciton electron trap
2011/8/18
Abstract: CaF$_2$:Yb$^{2+}$ and SrF$_2$:Yb$^{2+}$ crystals have been investigated by a two-color UV + IR transient photoluminescence enhancement technique. The enhancement gives information about both...
Transient photoluminescence enhancement as a probe of the structure of impurity-trapped excitons in CaF$_2$:Yb$^{2+}$
photoluminescence enhancement impurity-trapped excitons Materials Science

Abstract: We demonstrate a direct measurement of the energy levels of impurity-trapped excitons in CaF$_2$:Yb$^{2+}$. The radically different radiative decay rates of the lowest exciton state and high...
Controlling single diamond NV color center photoluminescence spectrum with a Fabry-Perot microcavity
Controlling single diamond NV color center photoluminescence spectrum Fabry-Perot microcavity
2010/11/9
We present both theoretical and experimental results on fluorescence of single defect centers in diamond nanocrystals embedded in a planar dielectric microcavity. From a theoretical point of view, we ...
Si nanocrystals (nc-Si) are addressed in the eutectic Al2O3:SiO2 thin films co-doped with Er3+ and Yb3+ by the laser-induced crystallization (LIC). The thin films are originally synthesized on a silic...
Photoluminescence Characteristics of Gd2Mo3O9:Eu Phosphor Particles by Solid State Reaction Method
red emitting phosphor Eu3+ white LED Na2C03 rare earths
2011/12/7
Eu3--doped C;dzMo309 was prepared by solid-state reaction method using Na2C03 as flux and characterized by pow-der X-ray iliffractometry . According to X-rq diffraction, this material belonged to a te...
A Two-coordinate Copper(I) Complex Constructed from Cyanuric acid and 4,4′-bipyridyl: Synthesis, Structure and Photoluminescence
一价铜化合物 光致发光 三聚氰酸 联吡啶
2007/12/19
摘要 通过水热法合成了一个具有很强光致发光特性的两配位一价铜化合物，Cu(bipy)(H2L)2 1 (H3L = cyanuric acid, bipy = 4,4′-bipyridyl)。化合物结构通过单晶X−射线衍射所解析。化合物具有单斜 P21/n空间群，其晶胞参数为， M = 269.71、 a = 13.4806(5) Å、 b =4.5234(2) &Arin...
