The alexandrite effects of plutonium! In select elements, by changing the light emitting conditions, different colors are observed from the sample despite no chemical changes occurring! @Jsperling91 @TEAS_Actinides #Plutonium #colorfulchemistry #actinides

Overnight, Ostwald-ripening induced crystallization unexpectedly yielded the oxidized Pu(IV) species (in green) of yesterday's crystals. Although not photogenic, produced some very exciting data! #plutonium #fblockrocks @TEAS_Actinides
