By optimizing the Debye temperature, we identified two extremely efficient phosphors based on the S–P transition of Bi3+. The quantum yields of Sr0.99Ga1.50B2O7:0.01Bi3+,0.50Al3+ and Ba0.995Ga1.60B2O7:0.005Bi3+,0.40Al3+ phosphors reach 96% and 99%, respectively. Moreover, Sr0.99Ga1.50B2O7:0.01Bi3+,0.50Al3+ exhibits negative thermal quenching, which shows unique advantages for practical application. The blue phosphors with quantum efficiencies close to unity and superior thermal stability can be competitive candidates for practical applications.
