Abstract

The invention belongs to the technical field of optoelectronic information, and particularly relates to a preparation technique of a nanometer crystal surface graph-strengthened light-emitting composite glass film. The preparation method comprises the following steps: sequentially preparing the glass film containing the light-emitting materials and the graphic film layer containing the metal materials, such as silver, gold or copper, on the glass, single-crystal or polymeric optical substrate surface; enabling the metal ions in the graphic film layer to directionally diffuse into the glass film containing the light-emitting materials and forming the metal (such as silver, gold or copper) nano-crystal in graphical distribution by employing the DC electric field induction thermal transfer printing technique; and improving the fluorescence efficiency of the light-emitting materials by adopting the surface plasma fluorescence enhancement effect of the metal nano-crystal, and further realizing the graphical light-emitting of the glass film. The nano-crystal enhanced graphical light-emitting film prepared based on the technique is applicable to the fields, such as optical information recording, displaying and processing.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic information, and in particular relates to a nanocrystal-enhanced patterned light-emitting glass film material on an optical substrate and a preparation technology thereof. Background technique [0002] Luminescent glass film materials are obtained by introducing various luminescent substances such as rare earths, semiconductors, metal ions and nanocrystals into the optical glass film matrix with stable structure and excellent optical properties, so as to obtain various unique luminescent properties. Compared with some organic light-emitting materials, light-emitting glass film materials have the characteristics of good chemical and thermal stability and long service life, and have been widely used in information display, storage, transmission, processing and other fields. Luminescent glass film materials require that the glass matrix should have good structural stability, easy introduction ...
