Composite ceramic materials are solid-state light converters (phosphors) that canLED systems based on them allow you to use them in terrestrial and aerospace technologies.Save 20-30% more energy compared to commercial counterparts.Details about the study are reported by Materials Characterization.
More than 15% of total world productionelectricity, or about $ 450 billion a year, is spent on lighting. According to the roadmap for the development of photonics in Russia, the development of LED technology with an efficiency of more than 150 lm / W will save up to 30% of electricity by 2025.
Based on developed ceramiclight converters can be produced as compact white energy efficient light-emitting diodes (wLEDs) and high power systems (high brightness). The new material is in demand in many photonic applications: from portable projectors and endoscopes to laser TVs with a diagonal of more than 2.5 m, lighting devices for the automotive and aircraft industries, etc.

New materials are characterized by highvalues of thermal strength and thermal conductivity, withstand high pump power and generate bright white light without obvious thermal quenching of the photoluminescence intensity. This reduces the operating temperature of the LED device to 120–70 ° C - twice that of commercial Ce3 +: YAG samples.
