Abstract

We investigate the two-photon threshold of rare-earth up-conversion under concentrated sunlight, in a solar furnace that generates an irradiance of up to 2606 suns on the samples. One of the most efficient up-converters currently available, NaYF₄: Er³⁺ [1] was used. We established a threshold by experimentally observing the transition for up-conversion photoluminescence from a quadratic relation to linear relation as solar concentration was increased. We further investigated the role of energy transfer on the threshold, observing the same threshold for a higher Er³⁺ content of 50%, but a threshold that exceeds 2300 suns at 15% Er³⁺. In this way, a tangible limit for the benefit and effect of solar concentration on up-conversion can be obtained for photovoltaic [2], [3] and solar thermal applications.
