Introduction: In our work we report the preparation, characterization and luminescence mechanism of Tb3+ activated LiBO2 green emitting phosphor for solids state lighting. Tb3+ has been extensively used as green-emitting activator for luminescent phosphor materials; the excitation and emission spectra indicate that the prepared lithium borate based phosphor can be effectively excited by 353 nm, to showing a bright green emission at 545 nm corresponding to the f→f transition of Tb3+ ions. All the characteristics indicated that LiBO2:Tb3+ is an excellent phosphor for solid state lighting.
