On the origin of fine structure in the photoluminescence spectra of the β-sialon:Eu2+ green phosphor
The photoluminescence (PL) and PL excitation (PLE) spectra of Si6−zAlzOzN8−z (β-sialon):Eu2+ phosphors with small z values (z=0.025–0.24) were studied at room temperature and 6 K. The PL and PLE spectra exhibit fine structure with the PL lines being as sharp as 45–55 nm even at room temperature; thi...
