“…In 2008, Naydenova et al reported the use of a photopolymer-based reflection hologram to produce a visual indication of environmental humidity i.e. detection of water vapour [16] and later zeolite doped holographic structures sensitive to toluene [17] and isopropanol [8] were reported. The incorporation of zeolites for improved holographic device sensitivity to organic vapours such as acetone [18] and ethanol [19] was subsequently investigated by Yu et al Both transmission mode [8] and reflection mode [20] polymer-based holograms have been developed for the real-time detection of gaseous volatile organic compounds (VOCs).…”

The suitability of holographic structures fabricated in zeolite nanoparticle-polymer composite materials for gas sensing applications has been investigated. Theoretical modeling of the sensor response (i.e., change in hologram readout due to a change in refractive index modulation or thickness as a result of gas adsorption) of different sensor designs was carried out using Raman-Nath theory and Kogelnik's coupled wave theory. The influence of a range of parameters on the sensor response of holographically recorded surface and volume photonic grating structures has been studied, namely the phase difference between the diffracted and probe beam introduced by the grating, grating geometry, thickness, spatial frequency, reconstruction wavelength, and zeolite nanoparticle refractive index. From this, the optimum fabrication conditions for both surface and volume holographic gas sensor designs have been identified. Here, in part I, results from theoretical modeling of the influence of design on the sensor response of holographically inscribed surface relief structures for gas sensing applications is reported.

Optical Materials, vol. 48, Oct. 2015, pp. 12-17. doi.org/10.1016/ j.optmat.2015 Determination of the polymerisation rate of a low-toxicity diacetone acrylamide-based holographic photopolymer using Raman spectroscopy t r a c tThe polymerisation rate of a low-toxicity Diacetone Acrylamide (DA)-based photopolymer has been measured for the first time using Raman spectroscopy. A value for the polymerisation rate of 0.020 s À1 has been obtained for the DA photopolymer by modelling the polymerisation reaction dynamics as a stretched exponential or Kohlrausch decay function. This is significantly lower than the polymerisation rate of 0.100 s À1 measured for the well known Acrylamide (AA)-based photopolymer composition. The effect of the additive glycerol on the polymerisation rate of the DA-based photopolymer has also been investigated. The inclusion of glycerol is observed to increase the rate of polymerisation of the DA photopolymer by up to 60%. It is also observed that the polymerisation rate of the DA photopolymer is less dependent on the recording intensity when glycerol is present.

They can be multiplexed, miniaturised, their response experiences little interference from external electromagnetic fields, they can be designed to perform remote sensing.…”

Zeolites are characterised by a highly porous structure with a pore size similar to the size of many industrially important molecules, and the trapping of a variety of chemicals in zeolites is well documented [5][6][7][8]. Due to the large variety of zeolite nanoparticles structure and chemical composition, the flexibility in their synthesis and the possibility to functionalise them, these nanoparticles are ideal candidates for incorporation in sensors.…”

A B S T R A C TEnvironmental monitoring has been continuously increasing due to an emerging global emphasis on the importance of sustainable development. Improving water quality monitoring and control is a challenge that calls for innovative solutions. Current methods of water monitoring are costly and analytical techniques suitable for field use are limited. There is a need for accurate, long-term monitoring of environmental contaminants using sensors that can be operated on site. The aim of our research is to theoretically model, fabricate and characterise holographic sensors for water quality monitoring that are simple to operate, capable of sensing copper present in fresh water and have relatively low cost. The sensors are created by holographic recording of surface relief gratings (SRG) in a self-processing photopolymer material. Interrogation of these structures by light allows indirect measurements of ion concentration in real time. The SRG structures are modified by coating with porous LTL-nanoparticles (nanosized zeolites) which selectively adsorb copper ions. The suitability of the sensors for detection of copper (II) present in water at concentration levels 1-4 mM is reported. The current detection limit of the sensor is 63 ppm.
