“…Divalent manganese is well known as a luminescence activator in zinc sulphide (see for example Klick andSchulman 1957, Langer andIbuki 1965). With both photoluminescence and cathodoluminescence excitation (Beserman and Balkanski 1971) the manganese emission band is centred at about 5860 A. The position of the band is almost independent of temperature, but the width of the band at half-height varies from about 480 A at 300 K to about 360 A at 4.2 K. Thus the manganese emission band is considerably narrower than the bands associated with copper or silver impurities for example.…”

The excitation and emission spectra of manganese-doped single crystals of zinc selenide have been measured. At 85 K three excitation bands were observed with maxima at 5370, 5025 and 4650 Å. When excitation was provided with wavelengths lying within the 5370 Å band, the characteristic emission of Mn2+ was observed with a maximum at 5860 Å. When ultraviolet excitation was provided (mercury 3650 Å), a much broader emission was observed with a maximum in the range 6200-6300 Å. Two other emission bands can occur in the vicinity of the Mn2+ band; these have maxima at 6150 and 6400 Å. It is suggested that they are in fact the self-activated and low-energy copper emission of zinc selenide. These bands are excited preferentially by ultra-violet radiation and swamp the manganese emission.After heating in liquid zinc, the manganese emission cannot be excited in photoluminescence, although the characteristic manganese absorption processes still occur. The absence of the manganese emission is probably associated with Auger de-excitation processes in the presence of a high concentration of free electrons.

“…L'absorption et l'émission avec la participation de phonons ont été étudiées en particulier dans le cas de l'ion Mn 2+ dans ZnS [6]. Les spectres observés ont été interprétés [7] Le rapport de l'intensité des modes de vibration dus au manganèse à celle du mode TO du ZnS croît proportionnellement à la concentration en manganèse, et les fréquences restent inchangées. L'étude de la variation des, fréquences Raman en fonction de la température représentée sur la figure 2 montre un comportement particulier de chacun des pics : lorsque la température passe de 300 K à Mn, de structure cristalline purement cubique, montre que les phonons qui participent à l'émission sont ceux observés en diffusion de la lumière.…”

Le manganèse se substitue au zinc dans le sulfure de zinc. Les fréquences des modes de vibration dus à la présence du Mn ont été déterminées par diffusion de la lumière. L'émission entre des niveaux électroniques 6A1 → 4T1 du Mn a été analysée à 2,4 K. Les modes récurrents qui assistent cette transition sont les modes de vibration de l'impureté. Celui qui a une symétrie Ɖ1 est prépondérant par rapport aux autres. Afin de déterminer la structure cristalline du ZnS : Mn, nous avons étudié l'émission du ZnS : Mn purement cubique et contenant des fautes d'empilement. Les propriétés vibratoires des impuretés substitutionnelles : Cr52, Mn55, Fe56, Ni59 et Co59 dans le ZnS, ont été analysées par diffusion Raman. Un comportement analogue à celui du manganèse a été observé. Un simple défaut de masse ne peut expliquer correctement nos résultats, et nous devons tenir compte de la variation des constantes de force
