Inorganic Photoactive Materials

Another silicone bouncy ball synthesized in the last week of our undergraduate lab course at the institute of inorganic chemistry II @HHU_de

It's #LumimescenceFriday! Here, we show a bright red phosphor illuminated by UV-light. 🤩

#LuminescenceFriday Our undergraduate students test by green-emitting aluminum-morin complex under UV excitation for aluminum in their sample in their second inorganic lab course #C2.

Over the past two weeks we were delighted to host Professor @MarkusSuta @photoactive_Dus from @HHU_de as our guest. Professor Suta delivered insightful lectures to our PhD students on the fundamentals of photoluminescent materials and their tailored design

For #FluorescenceFriday we show you a Pr3+ doped phosphor, which is still in the synthesizing process. But you can already see the cyan luminescence, which it should show. Made by @Tom_Foerster_

For #FluorescenceFruday we are showing you a Cr3+ #phosphor. Our PhD @kinik_glsm could obtain this phosphor in a single phase for further temperature-dependent #luminescent measurements! #Chromium #transitionmetal #led #red

Some beautiful rare-earth free phosphor made by one of our bachelor students. #FluorescenceFriday

For #FluorescenceFriday, we present you a phosphor that was synthesized via a solid-state reaction by our bachelor student Clemens. 🧑‍🔬 The bright red colour at 614 nm is due to the activation of #Eu3+. 😍 #phosphor #whiteled #emitter #europium #felements #luminescence #LED #red

Today for #FluorescenceFriday we show you a manganese-based phosphor synthesized by our master student Max.

📢 Event-Alert: Es ist wieder so weit! Die #Infoveranstaltung "Chemie im Dorf" wird am 06. Dez. ab 13:30 Uhr in HS 6G stattfinden! Die Veranstaltung richtet sich vor allem an unsere 5. Semester, die auf der Suche nach einem passenden Thema für ihre Abschlussarbeit sind.

Flame colouring in the undergraduate lab course! 😊 Sparkling ✨ and stunningly colorful

Today on #FluorescenceFriday we are presenting some Terbium-activated phosphates. The compound was synthesized by our new Masterstudent Duong.

And another aluminothermy demonstration experiment with the group @DaumannL for the undergraduate students. This time it even works in rainy weather!🙌

It's #FluorescenceFriday, but today we want to show you the beautiful colors of Ag nanoparticles synthesized by @Chemie_HHU master students at @HHU_de in the lab course. @a_Gorengo and @Tom_Foerster_ are looking forward to the next groups and their colorfull solutions.

It's #FluorescenceFriday again. Today we show you Na3Y(BO3)2 doped with Pr3+ under excitation with 254 nm. Synthesized by @Tom_Foerster_

It's #FluorescenceFriday, so today we show you a Mn2+ doped sulfide synthesized by Lukas.

@HHU_de @kinik_glsm @Chemie_HHU

@photoactive_Dus @kinik_glsm @Chemie_HHU Okay, so first we thought it's a luminescent sweet potato or a dragon fruit. Now we think it's aventurine? Tell us more!

So guess now which red luminescent mineral stone this might be. Also the space group can be guessed by its shape! Fascinated about the crystallization in nature 🙌 #FluorescenceFriday
