Researchers in South Korea develop non-contact measurement method for oxygen concentration at high temperatures
Researchers at Pusan National University in South Korea say they have developed a contactless method for accurately measuring oxygen concentration at high temperature conditions by using the phosphorescence of europium-doped yttrium oxide (Y2O3:Eu3+), which is sensitive to the oxygen concentration.
The researchers note that existing oxygen concentration measurement technologies rely on contact measurements using probes, which cannot withstand high-temperature environments. Moreover, despite the availability of optical temperature measurement technologies, the organometallic materials they utilize degrade at temperatures above 120°C.
