Selected phototropic Ag‐halide‐containing glasses were heat‐treated and then centrifuged at high temperatures to eliminate the phase‐separated carriers of phototropy. Analyses of the sediment showed, in addition to Ag and halide ions, at least one additional component. On the basis of the results of the analyses, such ternary systems and similar related compositions were vapor‐deposited onto substrates. The resulting layers, 150 to 570 nm thick, were studied for phototropism. The best phototropic properties were achieved in the eutectic area of the ternary system Ag‐Br‐Cu.
