Bringing Phosphorescence to the Classroom: Fast and Simple Synthesis of SrAl₂O₄:Eu²⁺,Dy³⁺ Via Solution Combustion and Microwave-Assisted Synthesis Anna Haab (25144655) Jana Wacker (25144658) Stefan Schwarzer (20993304) Neuroscience Science Policy via solution combustion require prolonged high persistent luminescent phosphor functional afterglow material approximately 100 ninth standard classroom environments 2 </ sub 3 +</ sup temperature treatment successfully conducted state syntheses simple synthesis school visits rapid synthesis novel hands grade students conventional solid bringing phosphorescence assisted synthesis 5 min A novel hands-on experiment was developed to foster authentic scientific inquiry in chemistry among high school students. The experiment centers on the rapid synthesis and characterization of a persistent luminescent phosphor, SrAl₂O₄:Eu²⁺,Dy³⁺. In contrast to conventional solid-state syntheses that require prolonged high-temperature treatment, the adapted procedure allows students to produce a functional afterglow material in under 5 min, making it accessible and safe for standard classroom environments. This experiment has been successfully conducted with approximately 100 ninth-grade students during school visits. 2026-09-30T00:00:00Z Dataset Media 10.1021/acs.jchemed.6c00241.s002 https://figshare.com/articles/media/Bringing_Phosphorescence_to_the_Classroom_Fast_and_Simple_Synthesis_of_SrAl_sub_2_sub_O_sub_4_sub_Eu_sup_2_sup_Dy_sup_3_sup_Via_Solution_Combustion_and_Microwave-Assisted_Synthesis/34033412 CC BY-NC 4.0
