Questions related to Luminescence
Acidic luciferase: hi all, does anyone know of a luciferase system (other than Gluc) that exhibits decent luminescence at pH 4 if not lower? Thanks and much obliged

From Er3+:4I11/2 level there're two emissions, one is ~2.7 μm emission (Er3+:4I11/2 →4I13/2) and the other is ~1 μm emission (Er3+:4I11/2 →4I15/2). So my question is in order to get the...
