Survey of mammographic cassette light output

Australasian Radiology, 1999
The purpose of the present paper was to assess the variation in light output from clinical mammographic screens, particularly in relationship to age and radiographic usage. The light output from 156 mammographic cassettes from 17 clinical centres was measured on site using a novel light detector.

Optimized ITO/Ag/ITO multilayers as a current spreading layer to enhance the light output of ultraviolet light-emitting diodes

Journal of Alloys and Compounds, 2019
ITO/Ag/ITO multilayers were optimized at different annealing conditions and were employed as a current spreading layer (CSL) for 365 nm UVLEDs. The ITO (40 nm) layer gave a transmittance of 83.9% at 365 nm, while the ITO/Ag/ITO (13 nm/14 nm/23 nm ...

Broadband emission of single-phase Ca3Sc2Si3O12:Cr3+/Ln3+ (Ln = Nd, Yb, Ce) phosphors for novel solid-state light sources with visible to near-infrared light output

Ceramics International, 2019
Novel single-component phosphors Ca3Sc2Si3O12:Cr3+/Ln3+ (CSS:Cr3+/Ln3+, Ln = Nd, Yb, Ce) with broadband near-infrared (NIR) emissions are synthesized. Their phase structure, photoluminescence properties and energy transfer between Cr3+ and Ln3+ ions are ...

Absolute light output of scintillators

IEEE Transactions on Nuclear Science, 1997
The absolute light outputs of BGO, CsI(Tl) and some new Ce-doped crystals have been measured to an accuracy of about /spl plusmn/5% using calibrated XP2020Q photomultipliers and standard S3590.03 and S2740.03 photodiodes. The use of small crystals, 9 mm in diameter and 1 mm thick, reduces the corrections for imperfections in the light collection ...

Light output of EJ228 scintillation neutron detectors

Applied Radiation and Isotopes, 2011
The light output of neutron detectors based on the plastic scintillator EJ228 is studied as a function of neutron energy using a time tagged (252)Cf source. Calibration of the light output scale is performed by fitting the experimental distribution of Compton scattering events of photons from a (22)Na source with a response function obtained by ...

High output LED-based profile lighting fixture

IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011
Recent developments in power light emitting diode (LED) industry have made LEDs suitable for being efficiently used in high intensity lighting fixtures instead of the commonly used high intensity discharge (HID) lamps. A high output LED-based profile-light fixture is presented in this paper.
