TMSP  Tris(trimethylsilyl)phosphine


The liquid crystal display in use now has issues of narrow color gamut. It is said that such displays are only able to reproduce about 20% of the colors recognizable by human. Quantum dots have rapidly gathered attention as a technology that improves this level to 60%.
Dots currently serve as nano particles in semiconductor crystals consisting of CdSe; however, development of InP quantum dots has advanced rapidly as a next generation material.
This material is already seen in some products. In the manufacture of InP quantum dots, TMSP is generally used as the source of phosphorus. We developed a fundamental technology where PH3 gas is used as the ingredient and have succeeded in the efficient industrial manufacture of high purity TMSP.

In addition, we have sufficiently established a system for safe transport of TMSP, which is a pyrophoric substance, to customers overseas.
We ask the interested customers to try our TMSP. Also, solvents and capping agents used generally in this area, namely trioctylphosphine (P-8), trioctylphosphine oxide (PO-8), tributylphosphine (P-4), and ributylphosphine oxide (PO-4), are available in our product lineup.
