Poly(methyl methacrylate) (PMMA)-based luminescent materials are of prime interest for many new optoelectronic devices. This work presents the spectroscopic properties of PMMA-based composites containing KGd (WO4)(2): Yb3+/Er3+/Tm3+, KGd(WO4)(2):Yb3+/Tm3+ and KGd(WO4)(2):Yb3+/Er3+ powders. These systems exhibit effective multicolor up-conversion luminescence in VIS and NIR spectral range under 980 nm excitation. The vibrational properties of the composites were investigated for the first time using the mu-Raman spectroscopy. The obtained results suggest that the KGd(WO4)(2):Yb3+/Er3+/Tm3+&PMMA integrated system can be successfully used as a new phosphor for the up-conversion based optoelectronic devices.

Abstract
Poly(methyl methacrylate) (PMMA)-based luminescent materials are of prime interest for many new optoelectronic devices. This work presents the spectroscopic properties of PMMA-based composites containing KGd (WO4)(2): Yb3+/Er3+/Tm3+, KGd(WO4)(2):Yb3+/Tm3+ and KGd(WO4)(2):Yb3+/Er3+ powders. These systems exhibit effective multicolor up-conversion luminescence in VIS and NIR spectral range under 980 nm excitation. The vibrational properties of the composites were investigated for the first time using the mu-Raman spectroscopy. The obtained results suggest that the KGd(WO4)(2):Yb3+/Er3+/Tm3+&PMMA integrated system can be successfully used as a new phosphor for the up-conversion based optoelectronic devices.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
