Abstract

Thin film of ZnPcSn was developed as a prototype for ozone detector. This study aimed to investigate the relationship thickness of thin film of ZnPcSn along with resistance value toward ozone exposure. The ZnPcSn thin film was deposited on a printed circuit board (PCB) substrate with various thickness using vacuum evaporation technique. The morphology of the thin film was observed using scanning electron microscope (SEM). The SEM images of ZnPcSn thin film showed that thicker layer of thin film leaded to greater pore and uniform distributed layer. To obtain the resistance value, ZnPcSn thin film was exposed to ozone for 30 minutes continuously. Ozone was synthesized by ozonator from air. Thicker film with higher ZnPcSn content had more intensive interaction with ozone. Higher interaction with ozone leaded to the increasing value of generated current, indicated by the decreasing of the thin film resistance value. This result demonstrated  that the ZnPcSn thin film has promising potential as ozone detector.

Abstract

In this research has been developed multifasa diffraction pattern analysis technique with rietveld refinement method with case study of application of the technique on thin layer of PZT (PbZrxTi (1-x) O3) which has been synthesized with variation of 1, 2, and 3 hour annealing time. This interpretation technique begins with the determination of the background, then performed refinement parameter determinant of pattern change, peak shape, and intensity of diffraction. The parameters are, respectively, scaling factor, 2θzero, lattice parameter, gaussian peak shape constant, and gaussian-lorentzian, atomic position coordinates, and preferred orientation. The refinement results show that changes in peak shape constant give significant changes in residual values, whereas atomic and preferred orientation changes do not provide significant change in residual values.

Abstract

In this research an ozonator prototype has been built to produce ozone, consists of air pump, gas flowmeter, an ozone reactor, and a glass pipe of nozzle. The most important part of the device is the reactor which consisting three main parts; 5 mm alloy electrode connected to a high voltage generator in the form of electrical gas stove lighter, 1 mm copper negative electrodes connected to the ground and a glass plasma discarge. The ozone gas formed is flowed to a container consisting of methyl orange solution 20 ppm at wave lenght of 470 nm. The concentration of ozone is determined by spectrophotometry method. The ozonator is characterized by ozonation periode variation of 5, 10, 15, 20, 25, and 30 minutes with the voltage used 3,5 volt, voltage variation of 3, 4, and 5 volts and flow rate variation of 227, 363, 464, 662, 864, and 1060 mL/min at the voltage used 3.5 volt. The result showed that the longer period and the higher voltage used for ozonation, the higher the ozone gas produced. The concentration of ozone obtained in this research is 0.76 ppm reached at 363 mL/min with 20 minutes ozonation duration.
