Stimulated emission of Cr²⁺ ions in ZnS:Cr thin-film electroluminescent structures
First observation of stimulated Cr²⁺ emission in ZnS:Cr electroluminescent (EL) impact-excited thin-film waveguide structures is reported. The structures consist of the following thin films deposited on a glass substrate: a transparent In₂O₃:Sn electrode, an insulator SiO₂/Al₂O₃ layer (~270 nm),...

| description |
First observation of stimulated Cr²⁺ emission in ZnS:Cr electroluminescent
(EL) impact-excited thin-film waveguide structures is reported. The structures consist of
the following thin films deposited on a glass substrate: a transparent In₂O₃:Sn electrode,
an insulator SiO₂/Al₂O₃ layer (~270 nm), an EL ZnS:Cr film (~600 nm), the same
insulator layer, and an Al electrode. The stimulated character of the emission recorded
through the edge of the structure is evidenced by the following. With increasing the
applied voltage, a broad band with three waveguide mode maxima in the edge emission
spectrum changes into an intensifying and narrowing band. The maximum of this band is
the same as that of the Cr²⁺ emission band recorded through the face, i.e. through the
In₂O₃:Sn electrode (1.75 and ~2.6 µm at the Cr concentrations (5-7)*10¹⁹ and (2-
3)*10²⁰ cm⁻³, respectively). The five-fold narrowing is observed when increasing the
voltage by ~4% in the case of the lower Cr concentration. The voltage and frequency
dependences of the edge emission are stronger than those for the face emission. A small
manifestation of the gain occurrence in the ZnS:Cr TFELS is also observed in the face
emission. The possibility to create a new type of electrically pumped lasers with the
impact excitation mechanism is discussed.
