A novel approach to obtaining chlorine-silicate phosphors is developed. This method based on the synthesis in a microwave furnace is shown to provide the following advantages compared with the conventional procedures: (a) “warmer” color, (b) incr

The sol–gel method was used to obtain high-brightness crystal phosphors from SrTiO3: Pr3+ producing more than 1800 cd/m2. A ten-fold increase in the intensity of the main luminescence spectrum band at λ = 617 nm by doping SrTiO3: Pr3+ was achieved
