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.

The influence of laser light on the yield of potato
, 2002 Since 1999-2000 year, on the field of Institute of Southern crops-Strumica, on aluvial soil with neutral soil reaction, has been investigated the laser treated end untreated potato seed materials in two experiment, which were established on the randomized blokes in the three repetitions.

Loss of quantum yield in extremely low light
Planta, 2004It has generally been assumed that the photosynthetic quantum yield of all C3 plants is essentially the same for all unstressed leaves at the same temperature and CO2 and O2 concentrations. However, some recent work by H.C. Timm et al. (2002, Trees 16:47-62) has shown that quantum yield can be reduced for some time after leaves have been exposed to ...

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.

Scintillation light yield of BaF2:Ce
Optical Materials, 2009Abstract BaF 2 :Ce scintillator is a well-known, reasonably fast and efficient scintillator characterized by a decent stopping power and availability of large size crystals. In this communication we report scintillation light yield measurements on a number of BaF 2 :Ce samples cut from one larger boule.

Measuring the absolute light yield of scintillators
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005Abstract The absolute light yield of four different scintillation materials measured with two photomultiplier tubes and two avalanche photodiodes is presented. Commonly, the photoelectron yields and electron–hole pair yields are corrected for the quantum efficiency of the detector, as specified by the manufacturer, to obtain the absolute photon yield.

Light, photosynthesis and yield in blueberries.
2018Abstract In this chapter, a global vision of the physiology (functioning) of a blueberry plant is described with regard to the generation and distribution of carbohydrates. The factors that are involved in dry matter production and its partitioning among the various plant organs are discussed, as well as the effect of several environmental ...

Light yield improvement in lead tungstate
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005Abstract A new approach to the possibilities of increase in the light yield (LY) of scintillations in lead tungstate (PWO) is discussed. The abrupt LY decrease above 200 K is connected with the start of rotations of WO 4 tetrahedra which disturbs electrostatic separation between non-equilibrium electrons and holes, thus accelerating their non ...

Determination of the scintillation light yield for NaF
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1988Abstract An upper limit of the scintillation light yield for a NaF crystal is determined by means of a separate scintillators measurement in the single-photon method. The upper limit thus found using a 60 Co source is equal to 10 −6 of that of NaI(Tl).
