Novel SnO2/MnO co-doped phosphate glasses with tunable luminescence properties

Broad blue-green-red emissions of SnO2/Pr3+ co-doped phosphate glasses

“…This emission band occurs due to the T 1 → S 0 electron transition in SnO 2 . The result is in accord with our previous study [6,9,10]. Under the same 267 nm excitation, the Pr 3+ single-doped sample shows an intense emission band at 320 nm.…”

“…75P 2 O 5 -25SrO is the same as our previously prepared ones [9,10]. These glasses co-doped with SnO 2 and Pr 3+ were prepared from high purity compounds (NH 4 H 2 PO 4 , SrCO 3 , SnO 2 , AR and Pr 2 O 3 , 99.99%).…”

“…Because oxide glasses possess advantages of transparency over the UV and visible wavelength range and ease of preparation, they have proved to be one of the most suitable host matrices. Our previous work has demonstrated that the SnO 2 doped phosphate glasses exhibit a broad 420 nm emission band upon 267 nm UV excitation [9,10]. Similar to SnO 2 , Pr 3+ can be also UV light excited and since its blue excitation bands overlap the emission band of SnO 2 [9], an ET between SnO 2 and Pr 3+ is likely to occur.…”

“…The semiconductor particles or quantum dots (QDs) may act as a sensitizer for rare earth (RE) or transition metal (TM) ions. The efficient excitation of RE or TM ions via the energy transfer (ET) from semiconductor QDs have been the cutting-edge research these days [7][8][9][10].…”

Multi-wavelength-driven solar spectral conversion in P2O5–ZnO–Li2O glasses for improving greenhouse photosynthetic activity

“…As a result, their emission bands could be tuned by adjusting the coordination field of Sn 2 þ [13,14]. Recently, Liu et al investigated the photoluminescence properties of SnO 2 /MnO co-doped 75P 2 O 5 -25SrO glasses, and interesting results were obtained [16]. In SnO 2 -doped glasses, optical transitions from the valence band to the conduction band are considered to be the emission centers, and the emission origin originating from Sn 4 þ or Sn 2 þ cations has not been fully clarified yet.…”
