什麼是PL?
PL (Photoluminescence, 光致發光):當材料吸收光子後,電子躍遷至激發態,再回到低能態,將能量以光的形式發出。
什麼是PLQY?
PLQY (Photoluminescence Quantum Yield, 光致發光量子產率) 計算方式為發出的光子數除以吸收的光子數。PLQY是評價發光材料的重要指標,除了可以用來對材料進行初級分類的基本參數,且對於發光系統與其載子動力學的重要分析方法。
LQ-100X-PL如何測試PLQY?
- 檢查背景訊號
- 檢查樣品
- 計算樣品的光致發光量子產率:

PL與PLQY是研究材料表徵的重要工具,目前材料測試面臨挑戰有以下三點:
(1) 無法在手套箱內測試。
(2) 無法進行原位時間光譜解析。
(3) 紅外波段擴展不易。
LQ-100X-PL針對上述的3大痛點,做出了應對。
Feature 快訊!10個太陽光強度的PLQY系統

LQ-100X-PL所搭配的激光器系統,能在3mm的光斑下,實現超過10倍Sun的光強激發,這一特性使其在PLQY(光致螢光量子效率)和QFLS(準費米能級分裂)研究中無往不利。在QFLS研究中,使用10倍Sun的光激發來測量PLQY是至關重要的。高激發強度能有效提高載流子濃度,使材料的激發態與實際運行條件更接近,這有助於獲得更準確的PLQY數據,從而更精確地評估太陽能電池的效率潛力。
此外,高光強激發還能抑制非輻射復合過程,增強輻射復合路徑的影響,從而減少PLQY測量中的偏差。同時,強激發下的PL信號較強,有助於降低測量誤差,提升數據精度。
在QFLS(準費米能級分裂)研究中,需要使用10倍Sun的光激發來測量光致螢光量子效率(PLQY),這主要是因為高光激發強度可以提高載流子濃度,從而達到類似於實際運行條件下的狀態。這樣做的原因包括以下幾點:
- 非輻射復合的抑制:在低激發強度下,非輻射復合路徑可能主導載流子的復合過程,使得PLQY偏低。隨著激發強度的增加,輻射復合路徑的影響增強,非輻射復合的比例相對減少,從而更準確地反映材料在高光強下的性能 。
- 激發態的穩定性:10倍Sun的激發強度可以使得載流子濃度達到一定水平,這時候材料內部的激發態和載流子動力學更接近實際工作時的條件,從而提供更準確的PLQY數據,這對於估計太陽能電池的潛在效率至關重要 。
- 實驗技術要求:由於在高光激發下,PL信號較強,這可以減少儀器測量的誤差,如背景噪音的干擾,從而提高數據的精確度。
總之,使用10倍Sun的光激發來測量PLQY是為了確保測量條件能夠模擬實際工作環境,從而得到更準確的材料特性數據。
特點
LQ-100X-PL擁有以下幾點優勢,可應對材料測試面臨的挑戰:
- 以緊湊的設計,尺寸大小 502.4mm(L) x 322.5mm(W) x 352mm(H),搭配4吋外徑PTFE材質的積分球,並且整合NIST追溯的校準,讓手套箱整合PL與PLQY成為可能。
- 利用先進的儀錶控制程式,可以進行原位時間PL光譜解析,並且可產生2D與3D圖表,説明使用者可以更快地表徵材料在原位時間的變化。
- 系統光學設計可容易的做紅外擴展,波長由700-1100nm, 可展延至1700。粉末、溶液、薄膜樣品都可相容測試。
實證
PL 光譜顯示

LQ-100X-PL系統可以針對多種材料進行PL與PLQY測試。步驟如下:
-
- 檢測背景訊號,如圖中藍色曲線,並可計算入射激發光子總數。
- 檢測樣品光譜,如圖中綠色曲線。計算得到發射光子總數。
- 計算 2. 步驟中,樣品吸收光子率與吸收光子總數。
- 由1. 3. 相除可得到PLQY。
發射光譜分析

LQ-100X-PL軟體可以針對PL發射光譜進行多種分析,以定量的表徵材料的特性。包含:
- 發光CIE色座標
- CIE-xyz
- CIE-XYZ
- CIE-uv
- 色溫
- 色彩純度
原位時間解析PL光譜變化

LQ-100X-PL除了PLQY檢測外,還可進行PL光譜隨時間變化連續測試,並繪製成2D或3D顯示圖-稱為原位時間解析PL光譜圖。
如圖所示,鈣鈦礦的PL光譜隨著時間增加的變化,可以波長半寬(FWHM)隨之增加,並且產生中心波長(Peak Lambda)紅移的現象。分析原位時間解析PL光譜圖,對於新型材料如鈣鈦礦的穩定性或亞穩態特性,具有直接的的證據說服力。是材料表徵的最佳工具。
