Abstract: The failure of hydrogen sensor with palladium film is primarily the phase transition of PdH. To restrain this, a novel palladium and yttrium (Pd-Y) alloy film was prepared by the co-sputtering method and was used to design an optical fiber hydrogen sensor. A sensor model was established based on the optical film matrix method. The relationship between the reflectivity of the film and the hydrogen concentration was discussed. The experimental results show that this sensor is superior to the traditional sensor w… Show more

“…The most commonly used transducers are based on Pd or WO 3 thin films. In these cases, the typical probe structures were associated to the intrinsic physicochemical characteristics of the sensing thin film that change according to the H 2 concentration, so the transmitted probe optical signal will also carry the corresponding signature through intensity evolutions [3][4][5][6][7][8][9][10] or wavelength shifts [11][12][13][14][15][16][17][18][19][20]. In addition, many other studies targeted the optical response modifications based on interferometers [21][22][23][24][25][26] or surface plasmon resonance [27][28][29][30][31][32][33].…”

“…In order to gain high activation energy to break Pd-H bonds, the concentration gradient between the thin film and the exposed environment should be sufficiently high enough to provide the necessary driving force [14]. However, pure palladium film is easy to bubble and crack after absorbing and desorbing hydrogen for several times [6], reducing the stability and reliability of the sensor. Mechanical stress in the film and lattice expansion of palladium structure are the significant issues for further research to address [7].…”

“…Pd-Y alloy thin film has been used to detect hydrogen gas based on both optical and electrical methods [6][7][8][9]15]. The electrical detection method is inexpensive, easy and convenient compared to the optical counterpart [6][7][8][9].…”
