On the measurement of luminescence excitation spectra

Journal of Luminescence, 1974
Abstract A method is presented for the unique determination of excitation spectra for non-linear luminescence, assuming only that the non-linearity occurs subsequent to absorption.

Femtosecond luminescence measurements in GaAs

Solid State Communications, 1986
Abstract We report luminescence measurements in GaAs with femtosecond time resolution. This represents more than an order-of-magnitude improvement over previous luminescence measurements and allows us to study initial relaxation processes of photoexcited carriers.

Reflection measurements for luminescent powders

Physica B: Condensed Matter, 2018
Abstract Luminescent materials are useful in applications varying from lighting and display technologies to document security features and medical research, amongst many others. Measurement of the excitation range is an important consideration, and absorption bands are often determined from a decrease in the measured diffuse reflectance of the ...

Bayesian analysis of luminescence measurements

Radiation Measurements, 2015
Abstract The age equation sets luminescence dating as a method of absolute dating. However, it is also characterized by the introduction of a large number of uncertainties. To assess these uncertainties, we decided to proceed under a Bayesian approach.

CMOS Circuit Analysis with Luminescence Measurements and Simulations

32nd European Solid-State Device Research Conference, 2002
Hot-carriers in MOSFETs are responsible for timedependent near-infrared emission, synchronous with the switching transitions in CMOS circuits. Fast electrical waveforms propagating through integrated circuits can be effectively measured by means of high sensitivity solid-state photodetectors with sharp time-resolution.

Long-Pulsed Luminescence for the Measurement of Dissolved Oxygen

Applied Spectroscopy, 2014
Thin-film luminescent sensors were used to measure dissolved oxygen in picoliter volumes for the purpose of monitoring single-cell oxygen consumption rates, and that work served as the motivation for the development of the method described here.

The Measurement of the Luminescence of Fluoroscopic X-Ray Screens*

Journal of the Optical Society of America, 1949
The selection of a superior fluoroscopic screen for direct x-ray observation and diagnosis requires the measurement of the visual effectiveness of the shadows of objects on the screen. At clinical levels of excitation ZnS-CdS fluoroscopic screens are excited to brightnesses near the condition of cone to rod transition.
