✦ Synopsis

The temperature dependence of spectral holes burnt into a phycocyanin-doped ethylene glycol/water glass is investigated in the temperature range between 1.5 and 15 K. The data are well described by a power law with an exponent of 1.16 IO. 1. Chromoproteins thus behave very much the same as glasses doped with small impurity molecules.
