Abstract: A unit is provided which comprises a first substrate (1) and a second substrate (2). At least one optoelectronic component (4) containing at least one organic material is arranged on the first substrate (1). The first substrate (1) and the second substrate (2) are arranged relative to one another such that the optoelectronic component (4) is arranged between the first substrate (1) and the second substrate (2). In addition, a bonding material (3) is arranged between the first substrate (1) and the second substrate (2), which material encloses the optoelectronic component (4) and bonds the first and second substrates (1, 2) together mechanically. The bonding material (3) contains silver oxide in a proportion of more than 0 wt. % and less than 100 wt. %, preferably between 5 wt. % and 80 wt. % inclusive, ideally between 10 wt. % and 70 wt. % inclusive.

Abstract: To provide a melt glass (10) to seal capillary spaces (9) surrounding external current supply leads (8) of molybdenum passing to molybdenum foils (6) in a pinch or press seal (7) of a high temperature, for example incandescent halogen lamp, the melt glass (10) is made of 3-10% Bi.sub.2 O.sub.3, 25%-40% B.sub.2 O.sub.3, remainder PbO. The melt glass has low toxicity and is molybdenum-compatible. An additive of barium oxide, in up to 15% and preferably up to only about 10%, may be added to the PbO. All quantities in mol-percent.
