Effect of sensitizer on the luminescence of thermally stable Eu3+-activated metasilicate phosphor for solar cell applications

Cation vacancy-boosted BaZnB4O8:xEu3+ phosphors with high quantum yield and thermal stability for pc-WLEDs

“…28 Thus, Eu 3+ ions are considered good activators of red phosphors. 29–31 The final performance of high-power pc-WLEDs is directly determined by the properties of red phosphors. At an operating temperature of 423 K, the fluorescence quantum yield of most Eu 3+ -activated red phosphors in high-power pc-WLEDs is low and exhibits serious thermal quenching.…”

“…The popular rare earth luminescent host materials include vanadates, borates, and silicates. 31,34,35 Among them, borates are regarded as good candidates for luminescent materials owing to their advantages of simple preparation, stable chemical structure, low synthesis temperature and high luminescence efficiency. 36–39 Up to now, numerous rare earth doped borate phosphors have been reported.…”
