摘要: Abstract The intense anti-Stokes white emission of Li(K)P4O12 crystals was observed in vacuum under 808 nm excitation. Influence optical pumping power and ambient pressure on up-conversion properties have been investigated. It found that occurred at atmosphere. Its origin has discussed terms Nd2+-charge transfer luminescence occurring the limited thermal conversion irradiated vacuum.
