Uses of Europium in the study notes
- The red phosphor :Eu³⁺ inside fluorescent tube lights and CFL bulbs — europium paints the warm red that makes lamp light feel natural.
- Blue-emitting Eu²⁺ phosphors completing the red–green–blue trio of trichromatic lamps and some modern LED lights.
- Security printing: euro banknotes carry europium-based inks and fibres that glow red and blue under a bank-teller’s UV lamp.
- Colour phosphors of old CRT television screens, where europium helped build the picture tube’s glowing colours.
Where you meet it
- Switch on a classroom tube light or CFL bulb — europium’s red phosphor is glowing right now inside the white coating.
- Any euro banknote under a UV torch at a bank or money-changer flashes europium’s hidden red and blue glow.

Why is Europium important in Bangladesh?
The full study page connects Europium to Bangladeshi life — school labs, local industries, health and the NCTB syllabus. This quick-answer page is the fast summary; the element page is the full story.
Where will I meet Europium in the NCTB exam?
Questions on Europium's uses are a recurring pattern in Class 9–10 and HSC chemistry. The element page ends with six exam-style questions in both languages — practise those and this pattern stops costing marks.
