Abstract
Lithium-boron-aluminum (LBA) glasses doped with
N
d

+
and fluorides were produced. From the
absorption spectra, their Judd–Ofelt intensity parameters,
Ω

and spectroscopic quality factors
were calculated. Exploiting their near infrared temperature dependent
luminescence, we investigated their potential for optical thermometry
based on the luminescence intensity ratio (LIR) methodology. Three LIR
schemes were proposed, and relative sensitivity values up to
3.57
±

were obtained. From the temperature
dependent luminescence, we alternatively calculated their
corresponding spectroscopic quality factors. The results indicated
that
N
d

+
-doped LBA glasses are promising
systems for optical thermometry and as gain mediums for solid-state
lasers.
