Downconversion for the Er[super]3+, Yb[super]3+ couple in KPb sub(2Cl) sub(5) - A low-phonon frequency host

Downconversion of a single blue/green photon to two near-infrared photons offers a promising route to increase the efficiency of photovoltaic cells. Here we report on downconversion for the well-known upconversion couple (Er[super]3+, Yb[super]3+) doped into a host with low (200 cm[super]-1) maximum...
