Abstract

Photoluminescence (PL) of Er³⁺ doped in xNaO_0.5-xNbO_2.5-(100-2x)SiO₂ (mol%) (x = 24, 27, 30, 33, 36) glasses was investigated before and after crystallization. After crystallization, Er³⁺ was determined to be in the glass phase. Following the precipitation of the NaNbO₃ crystalline phase in these glasses, PL intensity of ⁴S_3/2→⁴I_15/2 transition of Er³⁺ increased. A maximum of >100-fold increment in the PL intensity was observed after crystallization as compared with that of the uncrystallized glass. The mechanism of augmentation of the PL intensity is discussed in terms of the theory of PL intensity. We assume that the difference in the refractive index between the residual glass and crystallized phases was a dominant factor causing the increase of the PL intensity after crystallization.
