Mn--Cr dopant association in dilute co-doped revealed by combined EPR and optical spectroscopy
Apoko S. Omondi, Mátyás M. Rudolf, Nikoletta Jegenyés +5
Efficient and durable phosphors made from abundant elements underpin energy-saving solid-state lighting, near-infrared light sources for sensing, and X-ray and biomedical imaging.…

Precursor stoichiometry controls dopant structure, defect chemistry, and valence in Mn-doped ZnGaO 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…
