Germanate and tellurite glasses have these characteristics and were identified as good hosts for trivalent rare-earth ions (REI) and metal or semiconductor nanoparticles (NPs) [1-12].

(Behind the Iron Curtain this trip was represented as a "lecture tour," and Martin's specimens, including benitoite and newly descfibed tellurites
and tellurates, were "samples" for the "lectures." Other "samples" included cigarettes, nylon stockings, etc.).
