Abstract

High-brightness orangish red fluorescence emissions were captured in Eu3+ doped fluorophosphate (NBFP) glasses with outstanding rare earth (RE) ion solubility under laser excitation. Highly efficient emissions of Eu3+ doped NBFP glasses in the wavelength range of 580-720 nm make the phosphors potential candidates as a remarkable orangish red lighting source. The net emission power and the net emission photon number in 6.0wt% Eu2O3 doped NBFP glass were derived to be 6.48 mW and 2.08 × 1016 cps under the excitation of 465 nm laser with 53.46 mW optical power, respectively, and total measured quantum yield was as high as 54.03%. When the excitation power was increased to 561 mW, the luminous flux of 6.0wt% Eu2O3 doped NBFP glass was up to 31.21 lm, demonstrating that Eu3+ heavy-doped NBFP glasses are potential lighting source materials. Thus, the laserdriven high-brightness phosphors originating from the sufficient photon release of Eu3+ ions promote further development of orangish red lighting source.
