準二維鈣鈦礦具有特殊的量子井結構以及非常高的量子產率，這對於雷射應用非常有益。然而，準二維鈣鈦礦中低維度相的形成可能會降低能量轉移效率。本研究發現，透過摻雜鈉離子作為有機間隔物能有效減少n=1相的形成，並且能夠抑制準二維鈣鈦礦中的非輻射複合損失。
在本研究中，我們採用具有CD週期結構的PFPE模具，透過溶液壓印法製作了高品質的準二維鈣鈦礦微米線，進而建構Fabry-Pérot共振腔。透過這種簡單方法，我們能夠生產出具有低雷射閾值和高品質因子的Fabry-Pérot雷射。
特別的是，透過角分辨的微光致發光光譜技術，可以觀察到微米線形成的Fabry-Pérot共振腔揭示了類似楊氏干涉實驗的現象。在這種情況下，微米線的兩個端點充當了雙縫實驗中雙縫的角色，從而推斷出Fabry-Pérot共振腔模式的奇偶性。

Quasi-2D perovskites possess a unique quantum well structure and exhibit exceptionally high quantum yield, which is very beneficial for laser applications. However, forming low-dimensional phases in quasi-two-dimensional perovskites can reduce energy transfer efficiency. This study found that doping Na+ (sodium ions) as organic spacers can efficiently minimize the creation of the n=1 phase and curtail non-radiative recombination losses in quasi-2D perovskites.
In this study, we used a PFPE mold with a CD periodic structure to create high-quality quasi-2D perovskite microwires through solution imprinting, thereby constructing a Fabry-Pérot resonator. Through this simple method, we were able to produce Fabry-Pérot lasers with low lasing thresholds and high-quality factors.
Especially, by using angle-resolved μ-PL spectroscopy, it was observed that the formed microwire Fabry-Pérot resonator revealed phenomena similar to Young's interference experiment. In this context, the two ends of the microwire acted as the double slits in the experiment, thereby inferring the parity of the Fabry-Pérot resonance modes.
