What was discovered
Demarçay suspected anomalous lines in samarium in 1896 and isolated europium in 1901 by fractional crystallisation.
Demarçay also certified the spectrum of the Curies' radium.
What it led to
- Red phosphor for colour televisions
- Fluorescent security marks on euro banknotes
- Luminescent probes in bioanalysis
Built on
- Demarçay's spectroscopy
- Fractional crystallisation
Made possible
- Trichromatic field-sequential colour TV system1940
- Fluorescent security ink
