Co-substitution Design: A New Glaserite-type Rare-earth Phosphate K2RbSc(PO4)2 with High Structural Tolerance
Co-substitution Design: A New Glaserite-type Rare-earth Phosphate K2RbSc(PO4)2 with High Structural Tolerance An alkali rare-earth phosphate K2RbSc(PO4)2 was successfully obtained by the derivative of glaserite-type K3Na(SO4)2 by co-substitution of K(1)O12→RbO12, K(2)O10→KO7, NaO6→ScO6 and SO4→PO4, meanwhile maintaining the original anionic framework. K2RbSc(PO4)2 exhibits a layered [Sc(PO4)2]∞ framework built by ScO6 octahedra and PO4 tetrahedra, with K and Rb resided in the interlayers.
PT symmetric single-mode line-defect photonic crystal lasers with asymmetric loss design
Abstract The exploration of parity-time (PT) symmetry in micro-/nano-cavity lasers has recently gained immense research interest. The PT symmetric phase transition to single-mode lasing has been achieved by arranging the spatial distribution of optical gain and loss in single or coupled cavity systems. In terms of photonic crystal (PhC) lasers, a non-uniform pumping scheme is usually employed to enter the PT symmetry-breaking phase in a longitudinal PT symmetric system.
Structure, optical and luminescent properties of anhydrous samarium iodate Sm3(IO3)9(HIO3)4
Structure, optical and luminescent properties of anhydrous samarium iodate Sm3(IO3)9(HIO3)4 Ruixin Guo, Changcheng Tang, Mingjun Xia, Lijuan Liu and Xiaoyang Wang Abstract A new non-centrosymmetric iodate crystal Sm3(IO3)9(HIO3)4 has been successfully synthesized by a hydrothermal method. The crystal structure is a three-dimensional network with samarium polyhedrons linked by iodate groups. It shows a moderate second harmonic generation response of 1.1 KDP.
Design and analysis of an InGaAs/InGaAsP quantum well microlaser with longitudinal periodical strain distribution for single-mode lasing
Abstract Single-mode lasing for small size semiconductor laser is significantly important in the on-chip optical signal processing, data storage, and dense optical integrated systems. This paper presents new, to the best of our knowledge, single-mode quantum well microlasers by distributing periodical strain along the longitudinal laser cavity. The quantum transmission line modeling (Q-TLM) method is employed to establish the model for strained microlasers.

Intrinsic zero thermal expansion in cube cyanurate K6Cd3(C3N3O3)4
Intrinsic zero thermal expansion in cube cyanurate K6Cd3(C3N3O3)4 Zero thermal expansion (ZTE) materials are rare, but intriguing property in precise optical devices against thermal fluctuation. Here, a new cube ZTE compound K6Cd3(C3N3O3)4, composed of conjugated [C3N3] rigid six-membered-rings and [CdN4] tetrahedra, was reported for the first time. Its thermal expansion coefficient is as small as 0.06 MK-1, which is one-order magnitude lower than that of commercial Invar alloy.

Synthesis, Crystal Structure and Optical Properties of a New Fluorocarbonate with Interesting Sandwich-like Structure
A new fluorocarbonate, Na3Zn2(CO3)3F, was synthesized under a subcritical hydrothermal method. Na3Zn2(CO3)3F crystallizes in the space group C2/c with a sandwich-like framework in which the stacked [Zn(CO3)]∞ layers are connected with one another by bridging F atoms and [CO3] groups alternately. Interestingly, each Zn atom is surrounded by one F atom and four O atoms, forming a distorted [ZnO4F] trigonal bipyramid, which is observed for the first time in the carbonate system.

“All-Three-in-One”: A New Bismuth-Tellurium-Borate Bi3TeBO9 Exhibiting Strong Second Harmonic Generation Response
A new nonlinear optical (NLO) material, Bi TeBO (BTBO), is successfully grown from high temperature solution method. BTBO crystallizes in a polar space group of P6 with a framework structure composed of [Bi O ] blocks, with TeO and BO interconnection.
Structural varieties in zinc telluro-phosphates: Syntheses, crystal structures and characterizations of Sr2Zn3Te2P2O14, Pb2Zn3Te2P2O14 and Ba2Zn2TeP2O11 - Dalton Transactions (RSC Publishing)
Three new zinc telluro-phosphates Sr2Zn3Te2P2O14 (1), Pb2Zn3Te2P2O14 (2) and Ba2Zn2TeP2O11 (3) were grown by flux method and their crystal structures were solved by X-ray diffraction method. Although all of three crystals crystallize into same space group P21/c with similar chemical compositions, they exhibit different topology structure types.
