Application on the Luminescence Characteristics of Nanoaluminate Rare Earth Long‐Lasting Luminescent Composite Materials in the Field of Ethnic Clothing

Abstract

In the changing process of garment development, nanoaluminate rare earth material has unique advantages as a new garment material, such as easier preservation and brighter color, changing the visual beauty of traditional clothing. In order to in-depth study the role of nanoaluminate rare earth long afterglow luminescent composite materials applied to ethnic costumes, this article uses material preparation methods, numerical analysis adjustment methods, and equipment parameter introduction methods to analyze nanoaluminate rare earths and simplify them and create a luminous composite material that can be used in the field of ethnic minority clothing. To study the luminescence characteristics of the composite material, CXHP samples with different doping concentrations of Cr ions were irradiated with an ultraviolet lamp with a center wavelength of 225 nm for 4.5 minutes, and after 12 minutes attenuation, the afterglow emission spectrum was studied. The results show that the sample has near-infrared afterglow emission ranging from 645 nm to 740 nm, and the two emission peaks are located at 680 nm and 700 nm, respectively. The performance of its application on clothing was studied again. The water consumption in the experiment was 1500 ml, and the grams of composite material added for the three times were 0.6 g, 1.2 g, and 1.8 g, respectively. The hanging dyeing method was adopted during the experiment. Through experiments, it can be obtained that when the composite material is 1.8 grams, the visual effect is more similar to the hue, brightness, purity, and other aspects of the clothing. This way, when combined with the composite material for secondary design, a better visual effect will be achieved. From the practical application level, it has been verified that composite materials can be used in ethnic costumes.
