Controlling the luminescence in K2Th(PO4)2:Eu3+ by energy transfer and excitation photon: a multicolor emitting phosphor


Santosh K. Gupta, B. Rajeshwari, S. N. Achary, A. K. Tyagi and R. M. Kadam
New J. Chem., 2020,44, 14703-14711

Abstract

This work highlighted green, red, and white light emission from a single K2Th(PO4)2 compound consisting of actinide and an alkali ion through defect, doping, excitation, and energy transfer manipulation.


FTIR combined with chemometric tools (fingerprinting spectroscopy) in comparison to HPLC: which strategy offers more opportunities as a green analytical chemistry technique for pharmaceutical analysis


Khadiga M. Kelani, Mamdouh R. Rezk, Hany H. Monir, Menna S. ElSherbiny and Sherif M. Eid
Anal. Methods, 2020,12, 5893-5907

Abstract

Herein, ATR-FTIR coupled to chemometrics was used to quantitatively determine active pharmaceutical ingredient combinations, and compared to the chromatographic techniques as HPLC on the light of the twelve principles of green analytical chemistry.

Abstract

Continuous research on metabolomics is of utmost importance in the field of anti-doping control, including updating the selection of the most appropriate markers of prohibited substances, test specimens and analytical strategies.


An energy band engineering design to enlarge the band gap of KTiOPO4 (KTP)-type sulfates via aliovalent substitution


Fei Yang, Lijuan Huang, Xiaoyu Zhao, Ling Huang, Daojiang Gao, Jian Bi, Xin Wang and Guohong Zou
J. Mater. Chem. C, 2019,7, 8131-8138

Abstract

The two fluoride sulfates RbSnFSO4 and RbSbF2SO4 derived from the famous commercial crystal KTiOPO4via aliovalent substitution exhibited remarkably enlarged band gaps.
