Fluorescence spectroscopy - Wikipedia
网页Fluorescence spectroscopy (also known as fluorimetry or spectrofluorometry) is a type of electromagnetic spectroscopy that analyzes fluorescence from a sample.
Fluorometer - Wikipedia
网页A fluorometer, fluorimeter or fluormeter is a device used to measure parameters of visible spectrum fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. [1] . These parameters are used to identify the presence and the amount of specific molecules in a medium.
Fluorometry - an overview | ScienceDirect Topics
网页Fluorometry is superior to spectrophotometry in terms of sensitivity and specificity. In general, the sensitivity of fluorescence is 10–1000-fold higher in comparison to absorbance measurements. Fluorometry was introduced in immunological assays to improve immunoassay sensitivity.
Fluorimetry: Principle, Instrumentation, Factors, Uses
网页2024年4月27日 · Fluorimetry is a scientific and analytical technique used to detect and measure the fluorescent light emitted by the sample (lying in the visible spectrum) with the aid of ultraviolet rays. Here, the wavelength of the emitted light by the substance is greater than the absorbed light. This phenomenon is called luminescence (cold light).

网页激光诱导荧光分析(laser-induced fluorometry)： 采用单色性极好，强度更大的激光作为光源的荧光分析法。 与一般光源荧光测定相比，灵敏度可提高2~10倍，甚至可进行单分子检测。
网页General. All fluorescence instruments contain three basic items: a source of light, a sample holder and a detector. In addition, to be of analytical use, the wavelength of incident radiation needs to be selectable and the detector signal capable of precise manipulation and presentation (Figure 5).
Fluorescence Spectrophotometry: Principles and Applications
网页Fluorescence spectrophotometry is a set of techniques that deals with the measurement of fluorescence emitted by substances when exposed to ultraviolet, visible, or other electromagnetic radiation.
Fluorometry - an overview | ScienceDirect Topics
网页Fluorometry is defined as the measurement of the emitted fluorescence light. Fluorometric analysis is a very sensitive and widely used method of quantitative analysis in the chemical and biological sciences.

Fluorometry - Vocab, Definition, and Must Know Facts - Fiveable
网页Fluorometry is an analytical technique used to measure the concentration of fluorescent substances by detecting their emitted light after excitation. This method relies on the principles of fluorescence, where certain molecules absorb light at specific wavelengths and subsequently emit light at longer wavelengths.
