Room temperature photoluminescence of (RE)NiO3 (RE=La, Y, Er, Ho, Nd and La1-xYx) Fotoluminescência à temperatura ambiente de (TR)NiO3 (TR=La, Y, Er, Ho, Nd e La1-xYx )

Room temperature photoluminescence of (RE)NiO3 (RE=La, Y, Er, Ho, Nd and La1-xYx) Fotoluminescência à temperatura ambiente de (TR)NiO3 (TR=La, Y, Er, Ho, Nd e La1-xYx )

The nature of visible photoluminescence (PL) at room temperature in amorphous (RE)NiO3 (RE=La, Y, Er, Ho, Nd and La1-xYx) is discussed. Powders of this system were prepared by the polymeric precursor technique. The presence of broad PL band emission spectra at room temperature indicated increasing s...
