Enhancement of photoluminescence emission of Gd3+ activated borate phosphors for phototherapy lamps: A review

Enhancement of photoluminescence emission of Gd3+ activated borate phosphors for phototherapy lamps: A review

In this review paper, we discuss about photoluminescence emission of Gd3+ in various inorganic phosphors. Narrow band UVB (NB-UVB) emission of Gd 3+ in 312-315 nm is well sought after in medical field to treat photo-responsive diseases like atopic dermatitis, vitiligo, psoriasis, etc. However, this...

Zusammenfassung:In this review paper, we discuss about photoluminescence emission of Gd3+ in various inorganic phosphors. Narrow band UVB (NB-UVB) emission of Gd 3+ in 312-315 nm is well sought after in medical field to treat photo-responsive diseases like atopic dermatitis, vitiligo, psoriasis, etc. However, this 4f-4f, 6Pj → 8S7/2 intra-configurational transition of Gd3+ is weak and hence needs to be sensitized. Suitable sensitizers like Bi3+, Pr3+ are found to enhance the PL emission of Gd3+. Such phosphors with sensitized Gd3+ emission is highly suitable for phototherapy lamps.
