-010Luminescence Characteristics of Y 2 SiO 5 : Tb Phosphor Particles Directly Prepared by the Spray Pyrolysis Method.-The photoluminescence characteristics of as-prepared (spray pyrolysis) and calcined Tb-doped Y 2 SiO 5 particles are investigated. The prepared Y 2 SiO 5 :Tb particles absorb excitation energy in the range from 220 to 325 nm and the maximum excitation wavelength is near 240 nm. The main emission peak is 538 nm. The optimum doping concentration is 4 at.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
