Selective low energy excitation of palladium(II)tetraphenylporphyrin (PdTPP) and palladium(II)tetrabromophenylporphyrin (PdBrTPP) in the presence of 2-chloro-9,10-di p-tolylanthracene (DTACl), respectively, can yield easily visualized upconversion fluorescence. The external and internal heavy atom effects were firstly found to significantly increase upconversion efficiency (Fuc) of emitter (DTACl) doped with PdTPP or PdBrTPP as much as 10 % under excitation of low power density at 60 mW/cm2.
在2-氯-9,10-二对甲基苯乙芘(DTACl)存在下,选择性低能量激发钯(II)四苯基卟啉(PdTPP)和钯(II)四溴苯基卟啉(PdBrTPP)可以产生易于观察的上转换荧光。首先发现外部和内部重原子效应显著提高了掺杂PdTPP或PdBrTPP的发射体(DTACl)的上转换效率(Fuc),在60 mW/cm²的低功率密度激发下提高了多达10%。
