Time-resolved optical stimulation of luminescence has become
established as an important method for measurement of optically
stimulated luminescence. Its enduring appeal is easy to see with
the number of materials studied growing from the initial focus on
natural minerals such as quartz and feldspar to synthetic
dosimeters such as i !-Al2O3:C, BeO and YAlO3:Mn2+. The aim of
time-resolved optical stimulation is to separate in time the
stimulation and emission of luminescence. The luminescence is
stimulated from a sample using a brief light pulse. The ensuing
luminescence can be monitored either during stimulation in the
presence of scattered stimulating light or after the light-pulse.
The time-resolved luminescence spectrum measured in this way can be
resolved into components each with a distinct lifetime. The
lifetimes are linked to physical processes of luminescence and thus
provide a means to study dynamics involving charge transfer between
point-defects in materials. This book is devoted to time-resolved
optically stimulated luminescence and is suitable for researchers
with an interest in the study of point-defects using luminescence
methods. The book first sets the method within the context of
luminescence field at large and then provides an overview of the
instrumentation used. There is much attention on models for
time-resolved optically stimulated luminescence, two of which are
analytical and the third of which is based on computational
simulation of experimental results. To bring relevance to the
discussion, the book draws on examples from studies on quartz and
a-Al2O3:C, two materials widely investigated using this method. The
book shows how kinetic analysis for various thermal effects such as
thermal quenching and thermal assistance can be investigated using
time-resolved luminescence. Although use of light sums is an
obvious choice for this, contemporary work is discussed to show the
versatility of using other alternative methods such the dynamic
throughput.
