【Abstract】 In this paper, we have studied the emission spectra from the thermally excited 3P 1 and 1I 6 states in SrAl 12 O 19 ∶Pr 3+ .The ratio of the emission intensities of 3P 1→ 3H 5 and 3P 0→ 3H 5 transitions is applied to measure temperature. It is also pointed out that the thermally excited 1I 6 emission plays an important role in decreasing the quantum efficiency of the 3P 0 visible emission.更多还原
