Spectroscopic Investigations of Multiple Environments in Er:CaWO4 through Charge Imbalance

Fabian Becker, Catherine L. Curtin, Sudip KC +4

We present a detailed spectroscopic study of the ${}^4{\mathrm{I}}_{13/2}$ and ${}^4{\mathrm{I}}_{15/2}$ Er${}^{3+}$ multiplets of Er:CaWO${}_4$ grown without a co-dopant. Using photoluminesce…
