Abstract :
Time domain phosphorimeters (TDPs) are usual system in chemical analytical research. This very high-cost and high volume kind of equipment is constituted by very complex optical systems and expensive excitation lamps, and their use is reduced to laboratory. In this paper, some improvement with application to TDPs is presented in order to reduce volume and cost. Final version of a TDP could be used such as portable equipment, allowing user to extend measure out of labs.
