金纳米颗粒作为利用表面等离子体共振的有前途的纳米加热器颗粒，已被广泛研究用于各种化学和医学应用，尽管纳米加热器的合适波长仅在可见光范围内，并且由于其相对较低的熔点，可能的最高温度受到限制。大约在十年前，一种被称为脉冲激光熔化液体（PLML）的技术被开发出来，以制造亚微米球形颗粒为主要产品。在此过程中，亚微米级的颗粒被激光有效地加热到熔点以上，这表明亚微米球形颗粒可以作为一种新型的加热颗粒，克服了金纳米颗粒的缺点。由于B4C具有比金更宽的光吸收波长范围和更高的熔点，本研究考察了plml制备的B4C亚微米球形颗粒作为纳米加热颗粒的潜力。根据与B4C颗粒接触的材料熔化引起的热改性，估计了激光辐照的最高温度。实验表明，B4C粒子在300-1100 nm波长范围内具有足够的响应，即使在2000 K以上的温度下也可以作为纳米加热器。因此，B4C亚微米球形颗粒可作为新型空间选择性加热颗粒。
Gold nanoparticles as promising nano-heater particles utilizing surface plasmon resonance have been extensively studied for various chemical and medical applications, even though the suitable wavelength for nano-heater is only in the visible range and possible maximum temperature is limited due to its relatively low melting point. About a decade ago, a technique called pulsed laser melting in liquid (PLML) was developed to fabricate submicrometer spherical particles as main products. In this process, particles in the submicrometer size range are effectively heated over the melting point by laser irradiation, indicating that submicrometer spherical particles can be developed as novel heater particles that may overcome the drawback of gold nanoparticles. This study examined the potentials of PLML-fabricated B4C submicrometer spherical particles as nano-heater particles since B4C has a wider optical absorption wavelength range and higher melting point than gold. From the thermal modification induced by melting the materials in contact with the B4C particles, the highest attained temperature was estimated by laser irradiation. This experiment showed that B4C particles have sufficient response in 300–1100 nm wavelength range and can act as nano-heater even at temperatures over 2000 K. Thus, B4C submicrometer spherical particles can be used as novel space-selective heater particles.
