A down converting serine-functionalised NaYF₄:Ce³⁺/Gd³⁺/Eu³⁺@NaGdF₄:Tb³⁺ photoluminescent probe for chemical sensing of explosive nitroaromatic compounds

Abstract

In this contribution, we explored a novel serine-functionalised NaYF4:Ce3+/Gd3+/Eu3+@NaGdF4:Tb3+ core–shell nanophosphor as a down-converting photoluminescent probe for efficient sensing of nitroaromatic explosives.

Synthesis of Cerium Tetrafluoride and Cerium Trifluoride Nanoscale Polycrystals from Ammonium Hydrogen Difluoride

“…Tashi et al reported a facile hydrothermal synthesis and characterization of hexagonal Eu 3+ doped and Eu 3+ /Ce 3+ co-doped NaGdF 4 nanophosphors and the influence of different radii of rare-earth ions on crystal morphology. Furthermore, on the basis of this study, they also demonstrated a Ser-CS (serine-functionalized NaYF 4 :Ce 3+ /Gd 3+ /Eu 3+ @NaGdF 4 :Tb 3+ core shell) nanophosphor for the effective detection of nitroaromatic derivatives …”

“…Furthermore, on the basis of this study, they also demonstrated a Ser-CS (serine-functionalized NaYF 4 :Ce 3+ / Gd 3+ /Eu 3+ @NaGdF 4 :Tb 3+ core shell) nanophosphor for the effective detection of nitroaromatic derivatives. 32 Also, the heating rate and the maximum reaction temperature needed to be controlled. When the heating rate reached above 8 K/s, CeOF would appear in the product, which was difficult to remove.…”

Application of palladium nanoparticle supported organo-kaolinite for 4-chloro-2-nitroaniline catalytic reduction and electrochemical detection

“…Nitroaromatic compounds are an important class of chemicals widely used in chemical industries. 1,2 They are the basic backbone of some pesticides and highly substituted derivatives are powerful explosives for military and civilian use. 2 They are also very useful reaction intermediates in organic synthesis.…”

“…This approach is used for the synthesis of polymers, dyes, pharmaceuticals, pesticides and cosmetics among others. 1,2,4 As a consequence, large amounts of nitroaromatic compounds from the chemical industry are discharged intentionally or unintentionally into the environment, with serious damages. 4,5 Being rarely produced naturally, their biodegradation is difficult.…”

PEI functionalized NaCeF4:Tb3+/Eu3+ for photoluminescence sensing of heavy metal ions and explosive aromatic nitro compounds

“… 39 Tashi et al fabricated down converting serine functionalized NaGdF 4 :Eu 3+ /Ce 3+ @NaGdF 4 :Tb 3+ core–shell nanomaterial for the selective and sensitive detection of picric acid. 40 Abbas and co-workers developed C-encapsulated three-dimensional Cu nano-pyramids (C@3DCu-PY) sensors for the control and monitoring of phenolic compounds. 41 Saleemi et al reported a novel OVs rich spinel ZnFe 2 O 4 micro-spheres (ZF-Ms) sensor for the effective detection of As 3+ metal ion present in underground water.…”
