摘要： A security or identification device comprises a membrane laser structure configured to be optically pumped. The membrane laser structure comprises a flexible emission layer comprising a gain material; and one or more structures formed in or associated with the flexible emission layer and configured to provide optical feedback in the emission layer to produce a laser light output having at least one property representing an identifier.

摘要： A light-emitting device includes an organometallic complex of the form Z-M-Z1, as light emitting material. M is Pd(0) or Pt(0) and Z is a nitrogen containing heterocyclic carbene ligand. Z1 is a phosphorus ligand or a nitrogen containing heterocyclic carbene ligand that may be the same as or different from Z. The light emitting device may be an organic light-emitting diode (OLED), a sensor, or a light-emitting electrochemical cell (LEEC).
