Intrinsic light yield and light loss coefficient of Bi4Ge3O12 single crystals
Optical Materials, 2014Abstract In this paper we present the scintillation properties of polished Bi4Ge3O12 (BGO) crystals grown by the Bridgman method. The light yield (LY) and energy resolution were measured using XP5200B photomultiplier. At 662 keV γ-rays, high LY of 9680 photons/MeV and good energy resolution of 8.6% were obtained for a 5 × 5 × 1 mm3 BGO sample.

Light, photosynthesis, quality and yield in blueberries.
2012AbstractThis chapter describes the physiology (functioning) of a blueberry (Vaccinium sp.) plant with regard to the generation and distribution of carbohydrates. Factors that are involved in dry matter production and partitioning among the various plant organs, and the effect of several environmental variables and management practices on dry matter ...

Study of the light yield of LuAP:Ce scintillating crystals
1996 IEEE Nuclear Science Symposium. Conference Record, 2002We have obtained optically clear samples of LuAP:Ce from the Institute of Physical Research, Ashtarak, Armenia, measuring up to 5/spl times/5/spl times/40 mm/sup 3/. The photo electron yield for a number of these samples was measured with a Philips XP2020Q photomultiplier tube, and 556 photo electrons per MeV was obtained for the best samples.

Iron sensitizer converts light to electrons with 92% yield
Nature Chemistry, 2015Solar energy conversion in photovoltaics or photocatalysis involves light harvesting, or sensitization, of a semiconductor or catalyst as a first step. Rare elements are frequently used for this purpose, but they are obviously not ideal for large-scale implementation.

Intrinsic energy resolution and light yield nonproportionality of BGO
IEEE Transactions on Nuclear Science, 2003The intrinsic energy resolution and nonproportionality of the light yield as a function of gamma ray energies, in the energy range of 14 keV to 1.33 MeV, were studied for small BGO (Bi/sub 4/Ge/sub 3/O/sub 12/) crystals at room and liquid nitrogen (LN/sub 2/) temperatures.

Optical fibers light yield and radiation damage
Nuclear Physics B - Proceedings Supplements, 1998Three types of optical fibers are used in high energy physics experiments. Scintillating fibers are used mostly for tracking. Wavelength shifting (WLS) fibers to get the signal out from scintillating tiles, which are used often in calorimetry. The third type of optical fibers are clear, typically made of quartz where the Cerenkov radiation in the ...

Responses of soybean yield and yield components to light enrichment and planting density
2010Light intensity intercepted by the soybean canopy during the reproductive period is an important environmental factor determining soybean yield components and grain yield. A 2-year field experiment was conducted to investigate the effects of light enrichment and its interaction with planting density on yield formation of soybean cultivars.
