Herein, we report the photoluminescence properties of Bi3+-sensitized BaYF5: 10mol%Eu3+ nanoparticles. TheemissionspectrafeatureEu3+ peakscorrespondingtotransitions from the 5D0 excited to 7FJ (J=1, 2, 3, 4) lower levels with two dominant emissions positioned in the orange-red (∼592 nm, 5D0→7F1) and deep-red (∼697 nm, 5D0→7F4) regions. Upon 265 nm excitation, the emission intensity increases with an increase of Bi3+ concentration up to 20mol%. Due to the energy transfer from Bi3+ to Eu3+ ions, the integrated intensity of Eu3+ emission in the Bi3+ co-doped BaYF5:10mol%Eu3+ is 216% stronger than in the Bi3+-free sample. Our findings demonstrated that BaYF5:Eu,Bi has potential in plant lighting technology due to strong emission in red and deep-red spectral areas.
