Luminescence Processes in Phosphors for Cathode-Ray Tubes and Lamps

Features and Operation of Hollow Cathode Lamps and Deuterium Lamps

This paper discusses the parameters which influence the operation of hollow cathode and deuterium lamps. Examples are given of how parameters can be selected in order to improve the quality of analytical results. Aspects of deuterium lamp operation for background correction are also covered.

Emission and Excitation Mechanisms of Phosphors

In this chapter, basic concepts involved in luminescencewill be discussed.Wewill take a closer look at a number of excitation mechanisms which are involved in generating luminescence and processes which lead to luminescence, taking illustrative examples from luminescentmaterials applied in fluorescent lamps and cathode ray tubes.With respect to fluorescent lamps, we will restrict ourselves to d...

Persistent luminescence in MSi2O2N2:Eu phosphors

In this work we study the persistent luminescence properties of europium-doped alkaline earth silicon oxynitrides (CaSi2O2N2, SrSi2O2N2 and BaSi2O2N2). All compounds show afterglow emission, with an emission spectrum which is similar to the steady state photoluminescence. The afterglow decay time for BaSi2O2N2:Eu and SrSi2O2N2:Eu is about 50 and 100 minutes respectively, while for CaSi2O2N2:Eu ...
