A method for producing a photoluminescent composition and the composition obtained, in particular form granular photoluminescent compounds, chosen in particular, and not exclusively, from the following families, based on an inorganic matrix and a doping ion, the photoluminescent composition being intended to be introduced with at least one filler into a transparent matrix. The method comprises a preparation step of: —choosing a first photoluminescent compound PH1 with a particle size range comprising a peak centered on a value P1 corresponding to a particle diameter D1, —choosing at least one second photoluminescent compound PH2 with a particle size range comprising a peak centered on a value P2 corresponding to a particle diameter D2, —choosing the diameter D2 equal to the maximum measurement M1 of the volumetric space V1 freed by the presence of at least four juxtaposed particles of diameter D1. The invention also relates to the composition, the use of said composition and a method for maintaining luminance above a given threshold.

This invention relates to the field of waste resource utilization technology, and in particular to a method for making bricks from virgin aggregates of construction waste and composite aggregates of industrial waste. The method involves nano-modifying the surface of waste rubber, transforming it from an inert filler into an active component; using an activator composed of sodium silicate, sodium carbonate, ammonium sulfate, and borax to optimize the gelation system reaction process; and pre-mixing the modified rubber particles, construction waste aggregates, fly ash, and activator to form a composite aggregate, which is then used to prepare lightweight bricks. This invention solves the technical problems of poor interfacial bonding between rubber and the inorganic matrix, low solid waste content, and difficulty in simultaneously achieving product strength and thermal insulation / sound insulation performance. The resulting bricks are lightweight, high-strength, low-shrinkage, and have excellent thermal insulation and sound insulation properties.

This invention relates to a fluorescent probe based on ceramic fluorescent composite particles, its preparation method, and its application. The ceramic fluorescent composite particles comprise multiple fluorescent nanocrystals and an inorganic material; the inorganic matrix is ​​derived from a mesoporous material, and the multiple fluorescent nanocrystals are dispersed within the pore structure of the mesoporous material; the ceramic fluorescent composite particles undergo sintering, causing the framework of the inorganic matrix to shrink and densify, resulting in partial or complete closure of the pore structure, thereby forming a dense coating layer on the surface of the fluorescent nanocrystals; the particle size of the ceramic fluorescent composite particles is 50–300 nm, and the density is 1.1 g / cm³. 3 Up to 6 g / cm 3 The fluorescent nanocrystals are loaded into the total mass of the ceramic fluorescent composite particles at a rate of 10 wt% to 35 wt%; the absolute quantum yield of the ceramic fluorescent composite particles is above 85%.
