Diethylamine fluorescence sensor based on silica hollow sphere photonic crystals

Abstract

In this study, based on silica hollow sphere photonic crystals (SHSPCs), a facile and selective fluorescence sensor for high-performance diethylamine detection was developed. It does not involve complicated integration of...

Oxygen Vacancies Induced by Pd Doping in Ni-P2O5/MoO3 Hollow Polyhedral Heterostructures for Highly Efficient Diethylamine Gas Sensing

“…3,4 DEA is an important chemical raw material for pharmaceutical precursors and is used in the production of medicines, insecticides, herbicides, color additives, and antifouling. 5,6 DEA is a serious irritant to the skin and eyes. 7 The Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) recognize the permissible exposure limits for DEA gases as 10 parts per million (ppm) and 25 ppm, respectively.…”

“…In the wake of global industrialization, harmful pollutants, smog, and toxic gases are released into the atmosphere, destroying the environment’s composition. , Therefore, maintaining a clean and healthy air environment is an urgent priority. It is not just sulfur dioxide and carbon monoxide that provide the greatest threat to the environment but also other gases and volatile organic compounds (VOCs) such as diethylamine (DEA), ammonia, formaldehyde, and others. , DEA is an important chemical raw material for pharmaceutical precursors and is used in the production of medicines, insecticides, herbicides, color additives, and antifouling. , DEA is a serious irritant to the skin and eyes . The Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) recognize the permissible exposure limits for DEA gases as 10 parts per million (ppm) and 25 ppm, respectively .…”

Dye-Encapsulated Lanthanide Metal–Organic Framework-Based Photonic Crystals for Multilevel Optical Anticounterfeiting Application

“…A notable example is a patterned material based on PCs of CdS and SiO 2 nanoparticles reported by Chen et al, where the structural color of the pattern changes with the change of incident angle, providing a variety of information-storage functions . Inspired by these two kinds of materials, the combination of responsive fluorescent materials and structural color PCs to construct composites can simultaneously maintain the dynamic optical response of fluorescent materials and PCs. , A successful example is the combination of quantum dots and PCs reported by Guo et al, in which the collective optical properties, including diffractive light abilities and fluorescence, are generated . So far, only a few reports have focused on the changes in the refractive index of MOF-based PCs reacting with analytes, which produce structural color changes for chemical sensing. , Moreover, no reports have been found on the development of related optical applications by combining fluorescent MOFs with PCs.…”

Novel polymer-based thermoresponsive photonic crystal sensors with broad wavelength shifts
