ABSTRACTThe luminescence of Tb-doped a-SiC:H thin films with different Tb concentrations under sub-bandgap photon excitation was investigated. Two independent processes were identified. The annealing induced activation of the Tb3+ and the inhibition of host-mediated non-radiative recombination paths. The integrated emission intensity is described by a rate equation model, considering these two. In this study, the luminescence enhancement with increasing annealing temperature is shown. The optimal Tb concentration and annealing temperature for the highest Tb-related light emission intensity is determined. Finally, a parameter proportional to the number of optically active ions is found through the aforementioned model.

Abstract An automated procedure is described for the measurement of ATP. This method, based on the linear luminescence response of firefly extracts added to ATP, is rapid, reproducible, and allows a relatively large number of samples to be run (up to 35/hr.). A procedure is also given for the preparation of the luciferin-luciferase system from dried firefly lanterns. Sample volumes required are small, and reading error is about ± 3%. Uniform timing of the addition of reagents and reading of light emission intensity for each sample are insured. Variables investigated include dilution of firefly extract, alterations in time after mixing sample and enzyme, linearity, cation, anion, and ADP and AMP interference.
