摘要：
1. A method of producing concentrated silver nanoplates that retain their shape after concentration with increasing optical density, comprising: adding a stabilizing agent to an unconcentrated solution, wherein the non-concentrated solution contains silver nanoplates, where each silver nanoplate has a plate shape, the non-concentrated solution has a maximum optical density at the first wavelength； the stabilizing agent includes a polymer based on polyvinyl and borate； an increase in the concentration of silver nanoplates in an unconcentrated solution to obtain a concentrated solution, wherein the concentrated solution has a maximum optical density at the second wavelength and the maximum optical density of the concentrated solution is higher than the maximum optical density of the non-concentrated solution, and at least part of the silver nanoplates present in the non-concentrated solution retains lamellar form in a concentrated solution. 2. The method according to claim 1, characterized in that the increase in concentration is carried out using filtration in a tangential flow, while the maximum optical density of the concentrated solution is at least ten times the maximum optical density of the non-concentrated solution, the maximum optical density of the concentrated solution is at least 100 see, the polymer based on polyvinyl includes at least one polymer from the group consisting of polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA), borate includes sodium borate, the second1. Способ получения концентрированных серебряных нанопластин, которые сохраняют форму после концентрирования с увеличением оптической плотности, включающий:добавление стабилизирующего агента в неконцентрированный раствор,при этом неконцентрированный раствор содержит серебряные нанопластины,где каждая серебряная нанопластина имеет пластинчатую форму,неконцентрированный раствор имеет максимальную оптическую плотность при первой длине волны；стабилизирующий агент включает полимер на основе по
