Synthesis, crystal structure, and optical properties of a novel pentaborate, K2NaZnB5O10

Electronic properties and europium ion photoluminescence behaviors in Sr2CeO4 phosphor

“…CASTEP [25][26][27] used in the present work was on the basis of plane waves and pseudopotentials. The lattice optimization for the Sr2CeO4 was performed by using CASTEP code.…”

Crystal structures of the solid solutions Na3Zn0.912Cd0.088B5O10and Na3Zn0.845Mg0.155B5O10

“…The crystal chemistry of the resultant borates is rich, including infinite chains, sheets or networks for the anionic groups. For instance, in a series of pentaborates with general composition A 3 MB 5 O 10 (A = Na, K; M = Mg, Zn, Cd, Co, and Fe), at least three kinds of structure types have been reported, including K 2 NaZnB 5 O 10 in space group C2/c (Chen et al, 2010), -Na 3 ZnB 5 O 10 , Na 3 CoB 5 O 10 and K 3 MB 5 O 10 (M = Zn, Cd) in space group P2 1 /n (Chen et al, 2007a;Strauss et al, 2016;Yu et al, 2011), and -Na 3 ZnB 5 O 10 as well as Na 3 MB 5 O 10 (M = Mg, Fe) in space group Pbca (Chen et al, 2007b(Chen et al, , 2012Strauss et al, 2016). All of the structures contain polyborate anionic groups [B 5 O 10 ] 5À , which combine with different A + and M 2+ cations.…”

Efficient photodechlorination of chlorophenols on polarized MZnB5O10 (M = Na and K) nonlinear optical materials

“…The crystal structures of KZBO, KNZBO, and NZBO belong to the monoclinic space group P21/n, C2/c, and P21/n [28][29][30] as confirmed by XRD analysis (Fig. 1) (Fig.…”

“…Herein, we demonstrate that stable and inexpensive M 2 O-ZnO-B 2 O 3 (M=alkali metal atoms) alkali borate crystals with non-centric structure (KZBO, KNZBO, and NZBO), which are generally reported as nonlinear optical materials [28][29][30], can also function as efficient UV-vis light-responsive photocatalysts for CPs dechlorination. The catalysts exhibit high efficiency in dechlorination of 2-chlorophenol (2-CP), 4-chlorophenol (4-CP), 2, 4-DCP, and 2, 4,…”
