Luminescent properties and reduced dimensional behavior of hydrothermally prepared Y2SiO5: Ce nanophosphors
DW Cooke, JK Lee, BL Bennett, JR Groves… - Applied physics …, 2006 - pubs.aip.org
Hydrothermally prepared nanophosphor Y 2 Si O 5: Ce crystallizes in the P 2 1∕ c structure,
rather than the B 2∕ b structure observed in bulk material. Relative to bulk powder,
nanophosphors of particle size∼ 25–100 nm diameter exhibit redshifts of the
photoluminescence excitation and emission spectra, reduced self absorption, enhanced
light output, and medium-dependent radiative lifetime. Photoluminescence data are
consistent with reduced symmetry of the P 2 1∕ c structure and are not necessarily related …
