Novel Er3+ doped phosphate glass-ceramics for photonics

In this invited proceeding, we report our latest results on the development of Er
³⁺
doped phosphate glass-ceramics. Those new glass-ceramics were processed using different techniques, such as direct doping of particles into the glass melt and glass-ceramics methods. First, we explain the challenges to balance the survival and dispersion of Er
³⁺
doped particles when preparing phosphate glass-ceramics using the direct doping of particles. Then, we discuss the impact of the glass crystallization on the luminescence properties of Er
³⁺
ions.
