Phosphor Heating during the Transformation of Radiation

The temperature of phosphor heating as UV radiation is transformed into radiation of the visible range is estimated experimentally. The effect of luminescence quenching as the phosphor temperature rises is used to estimate the degree of phosphor heating directly. It is shown that due to Stokes losses, the phosphor for an LED strip is heated to 15°C when radiation with λ = 337 nm is transformed inside it.
