Time Of Flight Method

The zero-field mobilities of oxygen ions in oxygen have been measured by the Bradbury-Nielsen time-of-flight method at temperatures of 194, 273 and 294 K and at pressures in the range 0�1-3�5kPa. The zero-field reduced mobilities of 0; and 0: have been determined to be 2�248�0�015 and 2'077�0'014cm2 s-1 V-1 at both 273 and 294K. The thermal equilibrium constant for the reaction 0; +02 +02 ;:t 0: +02 , obtained by fitting to the variation of the mobility with gas pressure, was found to be (3�4�0� 5) x 10-17 and (1�2�0�2) x 10-17 cm3 at 273 and 294 K respectively.

AbstractIn order to investigate the luminescence properties of Er3+in GaN and the effect of oxygen (O) on Er3+ -related emission in GaN:Er, erbium (Er) ions were implanted into single-crystal h-GaN grown on a c-axis sapphire substrate at an energy of 2MeV. Oxygen ions were subsequently coiniplanted into GaN with Er ions. The influence of oxygen on Er-related emission in GaN with a large yellow band was studied by comparing photoluminescence (PL) measurements of GaN:Er and GaN:ErO. It was found that the optimum annealing temperature to obtain maximum PL intensity was 1200°C and that the E3+a-related PL intensities from GaN:ErO samples were negligibly enhanced in comparison with the GaN:Er samples. The temperature dependence of PL intensity in GaN:ErO showed no appreciable difference from that of GaN:Er. But good correlation between Er-related and a large yellow band emission was observed in GaN. This indicates that codoped oxygen ions influence Er-related and yellow band emission in GaN

Effect Of Oxygen

Oxygen ions are the necessary condition for steel corrosion which occurs when the steel’s passive film is destroyed. Oxygen ions diffusion directly influences steel corrosion rate. The paper, starting from the steel corrosion mechanism, summarized the testing technology and the research progress of oxygen ions diffusion coefficient, analyzed the influencing factors and studied further the effect of oxygen ions diffusion on steel corrosion in concrete. The testing technology of oxygen ion diffusion coefficient is combined with the testing method of steel corrosion rate, and the relationship between oxygen ions diffusion coefficient and steel corrosion rate are established.
