Pure and doped crystals of meta-dinitrobenzene have been grown using a Brid
gman-Stockbarger method. We have investigated the influence of the dopant (
oxine, resorcinol) on the optical properties of the bulk and him samples ob
tained using crystalline fragments from the melt grown ingots. Transmission
variations reflecting the quality of the material are connected with the p
urity level and the growth conditions. (C) 1999 Elsevier Science B.V. All r
