The Trapping of Fluorescent Light Produced within Objects of High Geometrical Symmetry

Monte Carlo optimization of depth-of-interaction resolution in PET crystals

“…Specific attention is paid to the distribution of scintillation light along the edge of the crystal which is coupled to the position sensitive detector (i. e. photodiode), as this distribution is the main factor that determines the depth-of-interaction resolution. This work is an extension of previous work by others that optimize either the total amount of light seen on one surface of the scintillation crystal [5,6] or the time distribution of the detected scintillation photons [7].…”

“…can directly illuminate any crystal surface [5], and these photons will only illuminate a portion of the surface, as illustrated by Figure 4.…”

Dimpled Planar Lightguide Solar Concentrators

“…Luminescent lightguide concentrators were proposed more than sixty years ago as a means to amplify the signal of fluorescent radiation counters [47][48]. With the development of photovoltaics, luminescent guiding and concentrating was revisited as a means to cheaply concentrate solar energy without the need for trackers [3,[49][50].…”

Comprehensive analysis of escape-cone losses from luminescent waveguides

“…Instead, the usual approach, first described by Shurcliff and Jones [14], and used by almost all workers since, is to assume the per-emission escape-cone loss rate simply equals the proportion of the solid angle defined by the critical cone, C, out of the full solid angle of the sphere, 4π. That is,…”
