We present the results of an infrared study including ISOCAM images at 6.75 and 14.3 μm and near-IR DENIS images of large portions of the dark clouds Chamaeleon II (28 arcmin×26 arcmin) and Chamaeleon III (19 arcmin×18 arcmin). We have found 12 young stellar objects (YSOs) in Cha II, of which 8 are previously identified sources. ISO-ChaII28 identified with IRAS 1255-7651 and located at the center of the cloud is a Class I YSO with an infrared luminosity of ˜ 1.5Lsun. The new candidate YSO in Cha II, ISO-ChaII13 has a clear mid-IR excess with an infrared luminosity of ˜0.02Lsun indicating the probable presence of a young brown dwarf. Finally, no sources with IR excess has been detected in Cha III at our sensitivity limits.
