Hello @LatinXChem I'm Rhayane Margutti Rocha and this is my work "Self‑assembly of Naphthoic Acid Molecules and Eu3+ to Study Luminescent Properties of Langmuir Films in situ and in Langmuir-Blodgett Films". #LatinXChem #LXChemInorg #Inorg064 #Luminescence #Thinfilms

@WhittakerBrooks @LatinXChem Thus, the QY of these materials is around 50-90%.

@WhittakerBrooks @LatinXChem The relationship between light emitted and absorbed by a luminophore or luminescent material could be calculated through Quantum Yield. For instance, dyes have a strong emission and their molar absorptivity or molar extinction coefficient are high. Hence their QY values are high.

Hello teacher @SidneyRibeiro70. Look at our reaserch. 🥰 🙂

@WhittakerBrooks @LatinXChem Our materials are able of emiting in this conditions. Look at the photo!

@WhittakerBrooks @LatinXChem For the characterization of our LSC under 1 natural sun, It's possible that a matrix doped with upconversion luminophores doesn't show luminescence. This mechanism requires a higher incident power (which would be produced with optical mirror).

@WhittakerBrooks @LatinXChem Another use is in White LED, incorporating Eu(III) complex and Carbon-dot in the substrate. The film covers a blue LED and produces white light. These materials are downshifting type, they're easier to synthetize when compared with up- and downconversion luminophores

@WhittakerBrooks @LatinXChem Hi @WhittakerBrooks Thanks for your comment, I'm really excited. Nowadays, we're working with cylindrical luminescent solar concentrator, but the organosilane named d-Ureasil(600) has been tested for green LEDs doping with Tb(III) complex.
