转换发光纳米粒子主要是由氧化物、氟化物、卤氧化物等基质掺杂三价稀土离子（如Er3+ , Eu3+ , Yb3+ , Tm3+ , Ho3+ 等）得到，通过多光子机制将红外光转换成可见光，为反Stokes发光；具有发射谱线窄，寿命长，发光稳定性好，不易受环境影响，生物毒性低，化学稳定性高等优点；广泛应用于生物荧光标记和成像、激光器、太阳能电池、防伪技术等领域。 成分：NaYF4(Er/Tm,

Our TiS2 crystals are stabilized in 1T ohase (semimetallic phase). They are grown using two different techniques through chemical vapor transport (CVT) or flux zone growth (see description of these tw

Single crystal ReS₂ (Rhenium disulfide) crystals are developed at our facilities using chemical vapor transport or flux zone technique methods after 9 years of growth optimization to ensure anisotropi

14 years of growth optimization in chemical vapor transport (CVT) as well as flux growth lead to our flawless WS2 crystals: Our large size (~1cm in size) vdW WS2 crystals are treated as gold standards

Hafnium disulfide (HfS₂) is an indirect gap layered semiconductor in the bulk and becomes direct gap semiconductor in monolayer form.

Large size hexagonal phase GaTe (Gallium telluride) crystals have been developed at our facilities using three different growth techniques, namely Bridgman growth, chemical vapor transport (CVT)
