Eu-Doped Strontium Aluminate Phosphorescence

7 Minute ReadIntroduction In a previous post, the phosphorescent properties of several glow-in-the-dark decorative paints were evaluated. The active phosphor in these paints was likely to be europium-doped strontium aluminate. In this post, we examine the emission characteristics of doped strontium aluminate in more detail and record the phosphorescence spectra of these fascinating materials. Some Technical Background […]
