摘要

研究了 La0.95Nd0.05MnO3 在聚焦 808 nm CW（连续波）激光激发下的发光光谱特性。在可见光范围内记录到以 670 纳米为中心的反斯托克斯宽带发射，在红外线范围内记录到以 2000 纳米为中心的斯托克斯带。它们的强度随激发激光功率的增加而呈指数增长。本文从涉及 Mn3+-Mn4+ 离子对的间隔电荷转移机制的角度讨论了激光诱导发射的机理。

Laser-Induced Emission Spectra of La0.95Nd0.05MnO3 Nanocrystals

The luminescence spectral properties of La_0.95Nd_0.05MnO₃ were investigated upon irradiation with a focused 808 nm CW (continuous wave) laser excitation. An anti-Stokes broadband emission in the visible range centered at 670 nm and a Stokes band in the infrared range centered around 2000 nm were recorded. Their intensities increased exponentially with excitation laser power. The mechanism of laser-induced emission is discussed in terms of an intervalence charge transfer mechanism involving the Mn³⁺–Mn⁴⁺ ionic pair.
