fluorescence
英 [flʊə'res(ə)ns; flɔː-]
美[flʊə'rɛsns]
- n. 荧光；荧光性
词态变化
形容词: fluorescent;
助记提示
1. flu- + -or => fluor (originally meaning "a flowing, flow").
2. => fluor: an old chemistry term for "minerals which were readily fusible and useful as fluxes in smelting". => fluorite / fluorspar.
3. fluorspar ("calcium fluoride," modern fluorite), name of the mineral where it was first found.
4. fluor + -ine (chemical suffix). So named because it is isolated from fluor / fluorite.
5. fluor + -escence (-esce + -ence). Because in fluorspar (fluorite) he first noticed the phenomenon, on analogy of phosphorescence. => "glowing in ultraviolet light".
6. fluorescence => fluorescent.

英英释意
- 1. light emitted during absorption of radiation of some other (invisible) wavelength
英文词源
- fluorescence (n.)
- 1852, "property of glowing in ultraviolet light," coined by English mathematician and physicist Sir George G. Stokes (1819-1903) from fluorspar (see fluorine), because in it he first noticed the phenomenon, + -escence, on analogy of phosphorescence.
