鈣鈦礦電池TRPL測(cè)試數(shù)據(jù)
主機(jī)OmniFluo990為核心光譜采集，405nm ps脈沖激光器耦合顯微光譜模塊實(shí)現(xiàn)微區(qū)的PL和TRPL，77K顯微低溫樣品臺(tái)（溫控范圍：77.2-300K，液氮為冷媒）提供變溫測(cè)量環(huán)境。
鹵化物鈣鈦礦材料的顯微穩(wěn)態(tài)PL測(cè)量
激發(fā)源：405nm ps激光二極管，產(chǎn)生主峰在760nm左右的發(fā)射峰。其中在77K溫度下主峰是763nm，86000信號(hào)強(qiáng)度，在150K溫度下主峰是761nm，15000信號(hào)強(qiáng)度。溫度從77K到150K，峰位藍(lán)移了2nm，并且信號(hào)降低了。
鹵化物鈣鈦礦材料的顯微TRPL測(cè)量
激發(fā)源：405nm ps激光二極管，在77K和150K溫度條件下監(jiān)測(cè)760nm發(fā)射的壽命衰減曲線。通過(guò)右圖的對(duì)比也可以清晰的發(fā)現(xiàn)，150K的衰減明顯快于77K的衰減。
