Abstract
In this work, to control the content of dichroic complexes in film polarizers based on polyvinyl alcohol, a luminescent technique is proposed that allows us to estimate: the ratio of molecular and paired iodine centers in H-type polarizers at T = 4.2 K; of dichroic complexes caused by molecular and aggregated forms of the dye in L-type polarizers at T = 300 K. The use of this technique will make it possible in the future to establish the dependence of the properties of polarizers on the structure of dichroic complexes, not only in H-type or L-type film polarizers but also in mixed (H + L)-type polarizers, to create polarizers of various spectral ranges.
为了控制基于聚乙烯醇的薄膜偏振片中二色性络合物的含量，本研究提出了一种发光技术，使我们能够估算出：在 T = 4.2 K 时，H 型偏振片中分子和成对碘中心的比例；在 T = 300 K 时，L 型偏振片中由染料的分子和聚集形式引起的二色性络合物的比例。利用这项技术，今后不仅可以在 H 型或 L 型薄膜偏振器中，而且可以在混合（H + L）型偏振器中，确定偏振器的特性与二向色复合物结构的关系，从而制造出各种光谱范围的偏振器。
期刊介绍：
Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies.
Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
