Precursor stoichiometry controls dopant structure, defect chemistry, and valence in Mn-doped ZnGa${}_2$O${}_4$ nanocrystals

Mátyás M. Rudolf, Gábor Bortel, Nikoletta Jegenyés +5

The luminescence of doped nanocrystals is usually optimised through the activator; here we show that the host cation ratio is an equally decisive, and largely overlooked, design va…
