WebOct 1, 2024 · When using the lifetime decay approach, a phosphor's sensitivity, S τ, can be described as the relative rate of change of the decay time, τ, in respect to temperature, T. (1) S τ = − ∂ τ ∂ T τ · 100 % To achieve acceptable precision, phosphors should exhibit a greater sensitivity than 0.6 % K in the correct temperature range [ 27, 28 ].

WebStandard Phosphor Types Three criteria allow the choice of the most suitable phosphor type: • efficiency • emission spectrum • luminescence decay time Type Composition Light Emission Decay Time 90 % to 10 % 10 % to 1 % P43 Gd 2O2S:Tb Green / 545 nm 1 ms 1,6 ms P46 Y3Al 5O12:Ce yellow green / 530 nm 300 ns 90 µs WebExcitation of the blue-emitting phosphor alone would be unfavourable, as the sharply focussed cathode rays are absorbed by the blue phosphor to a small extent only, and its decay time is too short; also, direct excitation of the yellow-emitting phosphor alone would yield poor efficiency because the traps are emptied too rapidly by the heat … WebNov 29, 2024 · We present an imaging phosphor thermometry system using the time-domain intensity ratio technique and demonstrate surface temperature measurements … reddit puck streams
